En el año de 1.957 Oswaldo Ramirez en el primer Congreso Centro Americano de Dermatologia 
describio por vez primera una dermatosis encontrada en su Pais, el Salvador, con el nombre de "Los cenicientos, problema clinico". En 1.961 Convit y Colaboradores consideraron esta enfermedad una variante del eritema perstans y la denominaron Eritema Cronico figurado con Melanodermia. La enfermedad fue aceptada como una nueva entidad nosologica en el 5to Congreso Ibero Latino Americano de Dermatologia Celebrado en Buenos Aires en 1963 con el Nombre de Eritema Discromico Perstans. 

En Al año de 1.967 el mismo Oswaldo Ramirez describe un estudio epidemiologico de 139 casos bajo el nombre de Dermatosis cenicienta o Eritema Discromico Perstans. Despues de esta primera descripcion comenzaron a reportarse numerosos casos en MUCHOS PAISES. 
En la decada de los 80 algunos autores comienzan a especular la posiblidad de que el Eritema discromico Perstans es una variante del liquen plano. Algunos lo denominaron LIQUEN PLANO PIGMENTOSO, esto en base a las siguientes caracteristicas: 

1. El LIQUEN PLANO y el ERITEMA DISCROMICO PERSTANS tienen UN MISMO PATRON histopatologico: Una dermatitis liquenoide. 
2.) El liquen plano se presenta a veces como maculas grisaceas. 
3.) Se describieron casos de localizacion clinica con patron ZOSTERIFORME en ambas.. 
4.) Se han descrito casos de EDP asociados a medicamentos. 
5.) El tratamiento es bastante dificil en ambos. 

En 1984. Ramirez de nuevo hace una revison sobre todos los casos publicados y concluye que NO ES UNA ENFERMEDAD TROPICAL, sino de distribucion mundial, mas no la asocia con liquen plano. 

42 años despues la controversia continua e incluso algunos autores hablan de 2 variantes de Eritema Discromico Perstans, Otros continuan insistiendo en que deberia unificarse el criterio de esta forma: ERITEMA DISCROMICO PERSTANS, una variante de LIQUEN PLANO, bajo la sinonimia de LIQUEN PLANO PIGMENTOSO. Yo estoy de acuerdo con esto 100% En estas 43 referencias, los hechos.

In 1957 Oswaldo Ramírez, during the First Central-American Dermatology Congress in El Salvador; described for the first time a dermatosis found in his country, el Salvador, with the name "The Ashy. Clinical problem". In 1961, Convit et al. consider this disease as a variant ot erythema perstans and name it "Chronic Figured Erythema with Melanodermia". this disease was accepted as new nosologic entity in the Fifth Congress of the Ibero-Latin-American College of Dermatology in Buenos Aires in 1963 with the name of "Erythema Dyschromicum Perstans". 

In To the year of 1.967 the same Oswaldo Ramirez describes an epidemiologic study of 139 cases under the name of Ashy Dermatosis or Erythema Dyschromicum Perstans. After this first description they began to be reported numerous cases in MANY COUNTRIES. 
In the decade of the 80 some authors begin to speculate the probability that the Erythema Diyschromicum Perstans is a variant of the Lichen Planus. Some denominated it LICHEN PLANUS PIGMENTOSUM, this based on the following ones characteristic: 

1. The LICHEN PLANUS and THE ERYTHEMA DYSCHROMICUM PERSTANS have the same histopathological picture: A lichenoid dermatitis. 
2.) The lichen planus is sometimes presented as ashy macules. 
3.) Cases of clinical localization were described with ZOSTERIFORM pattern in both. 
4.) Cases of EDP associated to medications have been described. 
5.) The treatment is quite difficult in both. 

In 1984. Ramirez again makes a revision on all the published cases and it concludes that it IS NOT A TROPICAL ILLNESS, but of world-wide distribution, but it doesn't associate it with lichen planus. 

42 years later the controversy continuous and some authors even speak of 2 variants of Erythema Dyschromicum Perstans, Others continue insisting in that it should become unified the approach in this way: ERYTHEMA DYSCHROMICUM PERSTANS, a variant of LICHEN PLANUS, under the synonymy of LICHEN PLANUS PIGMENTOSUM. I agree with this in 100%. In these 43 references, the facts.

ABSTRACT 
In 1957 Oswaldo Ramírez, during the First Central-American Dermato-Iogy 
Congress in El Salvador; described for the first time a dermatosis found in 
his country wjth the name "The Ashy. Clinical problem". In 1961, Convit et 
al. consider this disease as a variant ot erythema perstans and name it 
"Chronic Figured Erythema with Melanodermia". this disease was accepted as 
new nosologic entity in the Fifth Congress of the Ibero-Latin-American 
College of Dermatology in Buenos Aires in 1963 with the name of "Erythema 
Dyschromicum Perstans". 
According to O. Ramírez. "Erythema Discromicum Perstans (Ashy Dermatosis) 
is a chronic skin disease characterized by typical and marked changes in 
color of the skin (hyperpigmented macules, black-board gray, variable), of 
slow evolution, persistent, with no concomitant local alterations, but 
which sometimes have repercussions on the psychic state of the patient, 
according to the size of the lesion. It is not accompanied by any other 
cutaneous or symptomatic abnormality. It is not influenced by climate, 
racial, dietary or occupational factors". This dermatosis can appear at any 
age, from one to eighty years. Either sex can be equally affected, even 
though it is more frequent in females. lnitially lesions are localized, 
but they can become generalized, not involving scalp, annexes or 
palmo-plantar regions.

The typical clinical characteristic of the ashy dermatitis is the fact that 
in case of light colored skin, the grey colour remains invariable. There is 
a new clinical form which is called the Brown Cinder Dermatitis which is 
characterized by a disciplined localization in the center of the face, 
trunk or upper extremities together with an inexorable change of the grey 
colour at the beginning to a brown colour at the end on the other it, has 
be enhanced the existence of the nummular form which is characterized by 
the existence of many greyish independent spots of circular or oval form 
mainly at the level of the trunk.

An unusual case of ashy dermatosis of Ramirez occurred in a 5-year-old-girl 
who had ash-colored hyperpigmented macules and plaques on the left leg and 
the left side of the trunk. These unilateral lesions showed histopathologic 
changes of a lichenoid tissue reaction. Although the exact cause of ashy 
dermatosis remains unknown, the positive test result for serum rheumatoid 
factor and the granular deposition of IgM at the dermoepidermal junction 
found in our case has immunologic implications.

A clinical, histopathological, therapeutical and epidemiologic review of 
Ashy Dermatosis is done. This research has been taken from scientific 
publications, computers and personal communications. In twenty five years 
of scientific medical investigations it has not been determined its truth 
etiology , nor its therapeutic; this confirms it, as a new nosologic entity 
well defined. The epidemiologic researches are concludent that this is not 
a tropical disease exclusively, but one of all over the world. We hope to 
obtain more references on this dermatosis throughout the Sessions of 
Specialties of CILAD regarding this disease.

A 14-years-old girl suddenly developed typical dermal signs of 
ashy-dermatosis at the time of menarche. After one year, the signs began to 
fade and had disappeared completely two years later. The direct 
immunofluorescence and the ultrastructure resemble lichen planus. Endocrine 
factors may have played a part in the presented case, considering the 
sudden onset at the time of menarche.

11.) Erythema dyschromicum perstans and lichen planus. 
==================================================================== 
Arch Dermatol 1982 Sep;118(9):683-5 

Naidorf KF, Cohen SR 
Erythema dyschromicum perstans (EDP) is a cutaneous pigmentary disturbance 
originally considered to be a variant of erythema perstans. The nosologic 
identity of EDP has been challenged repeatedly as the number of patients 
with concurrent EDP-like eruptions and lichenoid disorders has increased. 
In this report, we describe a woman who had EDP for two years before the 
onset of classic lichen planus (LP). The active lesions of LP gradually 
evolved into typical ashy-gray macules of EDP. This case provides further 
support for the concept that EDP and EDP-like conditions should be 
classified, in certain instances, as erythema dyschromicum variants of LP. 

==================================================================== 
12.) Ashy dermatosis. An apoptotic disease? 
==================================================================== 
Arch Dermatol 1981 Nov;117(11):701-4 

Person JR, Rogers RS 3d 
Of nine patients with ashy dermatosis, eight were women; most were young 
adults when the dermatosis began. The incidences of atopy (five patients) 
and thyroid disease (three patients) were striking. Although some of the 
patients were clinically atypical, histologic study in all cases showed 
basal cell vacuolation, Civatte bodies, pigmentary incontinence, and a mild 
perivascular lymphohistiocytic infiltrate. Direct immunofluorescence 
microscopy, performed in four cases, showed igM cytoid bodies. We 
hypothesize that the postinflammatory hyperpigmentation in ashy dermatosis 
and, perhaps, in other dermatoses may occur on the basis of basal cell 
apoptosis.

13.) Ashy dermatosis--a variant of lichen planus?

Cutis 1980 Jun;25(6):631-3 

Kark EC, Litt JZ 
Immunofluorescence studies on a patient with clinical and histological 
evidence of ashy dermatosis revealed a pattern commonly associated with 
lichen planus. In view of these findings, the possibility of a relationship 
between ashy dermatosis and lichen planus is suggested.

J Dermatol 1999 Feb;26(2):119-21 
================================================================= 
Lee SJ, Chung KY

Korea. 

Erythema dyschromicum perstans (EDP) is a rare disorder characterized by 
asymptomatic, slowly progressive, ash-gray macular pigmentation of the skin 
which usually occurs from age 5 through adult life. We have experienced two 
cases of EDP in children aged 2 and 3, both exceptionally younger than the 
previously reported cases. We therefore suggest that EDP should be included 
in the differential diagnosis of pigmentary disorders occurring at an early 
age. 

================================================================= 
15.) Fixed drug eruption presenting as erythema dyschromicum perstans: a flare 
without taking any medications. 
================================================================= 
Dermatology 1998;197(4):383-5 

Mizukawa Y, Shiohara T 
Department of Dermatology, Kyorin University School of Medicine, Tokyo, 
Japan. 

Fixed drug eruption (FDE) can present as multiple pigmented macules that 
flare at fixed sites even when the patient has taken no medications. 
Although this presentation is not characteristic of FDE, it must be borne 
in mind in order to make a correct diagnosis. We describe such a patient 
whose condition was initially diagnosed as erythema dyschromicum perstans 
(EDP). Immunohistochemically intraepidermal T cells were distributed 
between basal and suprabasal keratinocytes in the lesional skin, a finding 
suggestive of FDE. A flare occurred not only with exposure to theophylline 
but also without exposure. A flare has never recurred and pigmented macules 
faded gradually after avoiding theophylline. On the basis of these 
findings, we recommend that patients with an EDP-like presentation be 
examined completely for causes such as drugs before labeling the cutaneous 
lesions.

16.) Reticulate postinflammatory hyperpigmentation with band-like mucin deposition.

Italy. 

BACKGROUND: Mucinoses of the skin are a group of disorders sharing 
accumulation of mucin in the skin or hair follicles. Postinflammatory 
hyperpigmentation, with pigmentary incontinence, is due to loss of melanin 
from epidermal basal cells and its accumulation in dermal macrophages. 
METHODS: We describe clinicopathologic features of two patients presenting 
with the association of pigmentary incontinence with an unusual diffuse, 
band-like dermal deposition of mucin, clinically presenting with reticular 
pigmented macular lesions. RESULTS: Two patients were observed with 
asymptomatic, persistent, reticular, pigmented patches located in the 
flexures, thighs, neck and back. Histology showed melanophages with a 
diffuse, band-like dermal deposition of mucin, an increased number of 
fibroblasts, a slight T-cell infiltrate and scattered mast cells. Blood 
markers of lupus erythematosus were negative. CONCLUSIONS: These findings 
may draw attention to pigmentary disorders such as lichen planus 
pigmentosus, erythema dyschromicum perstans, pigmentatio maculos eruptiva 
idiopathica, dermatopathia pigmentosa reticularis, prurigo pigmentosa and 
frictional melanosis. None of these entities, however, includes mucin 
deposition among its microscopic features. Macules were not preceded by 
erythema or any other lesions. We suggest that our cases could belong to 
group II of Rongioletti and Rebora's classification, i.e. they could be 
cases of secondary mucin deposition in postinflammatory hyperpigmentation, 
possibly in an unusual form of lichen planus pigmentosus or, less likely, 
frictional melanosis.

the literature.

Erythema dyschromicum perstans (EDP), described by Convit et al. in 1961, 
is a rare dermatosis. Its relationship with ashy dermatosis (AD), described 
by Ramirez in 1957, is still a matter of debate. We report a typical case 
of EDP. The patient, of North African origin, had a dyschromic (hypo- and 
hyperpigmented) eruption on the chest and limbs for 2 years. The lesions 
were occasionally surrounded by a papular border which spread slowly and 
centrifugally. Histological examination showed a lichenoid infiltrate. A 
carcinoma of the lung was simultaneously discovered. No treatment was 
given, EDP is infrequent and often considered identical to ashy dermatosis 
in the literature. However, the clinical aspects of the two diseases 
differ. The main features of these two diseases are reviewed and compared 
on the basis of a literature review. We conclude that EDP and AD are 
distinct clinical entities.

OBJECTIVES: To assess the expression of several cell adhesion and 
lymphocyte activation molecules in erythema dyschromicum perstans lesions, 
and to evaluate the effect of clofazimine therapy on the expression of 
these molecules. DESIGN AND METHODS: A prospective study. Skin biopsy 
samples were obtained from patients before and after 3 months of 
clofazimine therapy, and the expression of cell adhesion and activation 
molecules was assessed by an immunohistochemical technique. SETTING: This 
study was performed in a clinical referral center and an immunology 
research laboratory. PATIENTS: We studied 6 patients with erythema 
dyschromicum perstans. A diagnosis was made on the basis of clinical and 
histological criteria. Two patients discontinued participation in the 
study: one because of adverse effects and the other for unknown reasons. 
INTERVENTIONS: Patients were treated with clofazimine, 100 mg/d, for 3 
months. MAIN OUTCOME MEASURES: Expression of cell adhesion and lymphocyte 
activation molecules in skin biopsy specimens before and after clofazimine 
therapy. RESULTS: Before clofazimine therapy, we detected a noticeable 
expression of intercellular adhesion molecule 1 and major 
histocompatibility complex class II molecules (HLA-DR) in the keratinocyte 
basal cell layer. In addition, CD36, a thrombospondin receptor that is not 
expressed by normal skin, was detected in the strata spinosum and 
granulosum. The dermal cell infiltrate expressed the activation molecule 
AIM/CD69 and the cytotoxic cell marker CD94. After clofazimine therapy, the 
expression of intercellular adhesion molecule 1 and HLA-DR disappeared, as 
well as the mononuclear cell infiltrate. CONCLUSIONS: Our results suggest 
that some cell adhesion and activation molecules are involved in the 
pathogenesis of erythema dyschromicum perstans. Clofazimine appears to have 
an important effect on the inflammatory phenomenon of erythema dyschromicum 
perstans.

Erythema dyschromicum perstans is a rare idiopathic dermatosis 
characterized by ash-grey, well-demarcated skin lesions, which may involve 
the face. We describe an 8-year-old girl with erythema dyschromicum 
perstans presenting as bilateral acquired periorbital hyperpigmentation. 
The changes seen on histologic study of a skin biopsy specimen were 
consistent with the clinical diagnosis. The various causes of periorbital 
hyperpigmentation and characteristics of erythema dyschromicum perstans are 
reviewed.

A 53-year-old woman initially had lichen planus primarily on her 
extremities. Approximately 1 year later, lesions consistent with erythema 
dyschromicum perstans were observed. Both diseases cleared with 
griseofulvin therapy but returned after discontinuation of the drug. 
Retreatment with griseofulvin again resulted in clearing.

Immunopathologic studies of a patient with clinical and histologic evidence 
of erythema dyschromicum perstans revealed Ia antigen expression on 
epidermal keratinocytes, pronounced OKT4 and OKT6 staining of epidermal 
dendritic cells, and dermal infiltration of T lymphocytes of both 
helper-inducer (OKT4) and suppressor-cytotoxic (OKT8) phenotypes--a pattern 
commonly associated with lichen planus. These findings, taken in 
conjunction with positive IgG staining on colloid bodies, suggest the 
possibility that erythema dyschromicum perstans and lichen planus have 
similar disease processes.

Recently, a patient presented to us with skin that had areas of normal 
pigmentation, hyperpigmentation, and depigmentation. Workup eventually 
showed him to have simultaneously active lesions of a depigmenting 
disorder, vitiligo, and a hyperpigmenting disorder, erythema dyschromicum 
perstans.

Erythema dyschromicum perstans (EDP) and vitiligo are two cutaneous 
pigmentary dermatoses of unknown etiology. In the present study, the 
leukocyte infiltrates in the affected skin of EDP and vitiligo patients 
were studied using the avidin-biotin (ABC) immunoperoxidase technique and 
monoclonal antibodies which recognise the following mononuclear cell 
subgroups: T-suppressor/cytotoxic (CD8-Leu-2), T-helper (CD4 = OKT4), 
T-suppressor + macrophages (Leu-15), Pan T (CD3 = Leu-4), macrophages 
(Leu-M3) and Langerhans cells (CD1 = Leu-6), and other cellular markers 
such as Ia antigens and the Interleukin-2 receptor (CD25 = TAC). The 
immunocytochemical analysis showed a selective accumulation of CD3+, CD8+, 
Leu-15-, T-cytotoxic cells in the epidermis of both EDP and early lesions 
of vitiligo. In addition, an increase in the number of epidermal Langerhans 
cells (CD1+) was observed in some cases of EDP and vitiligo. The CD4/CD8 
ratios in affected and uninvolved skin for both disorders were not 
significantly different, although values lower than unity were only 
observed in the infiltrates of affected skin. Ia antigen positivity was 
observed in the dendritic cells of the dermis and epidermis, as well as in 
most of the lymphoid cells within the infiltrates for both diseases. 
Macrophages (Leu-M3) in EDP dermal infiltrates were generally found 
adjacent to extracellular melanin pigment. Lymphocytes expressing TAC 
(CD25) surface antigens were also present in the dermal infiltrates. These 
morphological observations suggest a possible immune cell participation in 
the dyschromia of such cutaneous disorders.

We studied 39 patients with erythema-dyschromicum-perstans-like 
dermatitis seen at Changuinola Hospital in Panama. They were compared 
with 41 controls. The 2 groups were native field workers of the banana 
plantations exposed to many pesticides. In 34 patients, there was a 
positive patch test reaction to 2,4,5,6-1,3- 
tetrachloroisophthalonilnitrile (chlorothalonil, TCPN) 0.001% in acetone. 
In 39 cases, biopsies showed a lichenoid tissue reaction compatible with a 
chronic pigmented dermatitis or erythema-dyschromicum-perstans-like 
dermatitis. Chlorothalonil is possibly the cause of the pigmented 
dermatitis observed in the 39 banana farm workers studied. Until 
additional studies are carried out, we consider this a possible rather 
than definite cause-and-effect relationship.

Lichen planus pigmentosus (LPP) has thus far been described as a 
condition of unknown etiology which clinically differs from the classical 
lichen planus (LP) by exhibiting dark brown macules and/or papules mostly 
in exposed areas and flexural folds and a longer clinical course without 
pruritus or scalp, nail or mucosal involvement. Histopathologically, LPP 
shows the typical changes seen in LP, but with thinning of epidermis. We 
report a case of LPP that developed in a unilateral, zosteriform pattern 
on the left flank of a 49-year-old man. This case seems to lie in the 
middle of the spectrum between classical LP and ashy dermatosis, and, to 
the best of our knowledge, is the first report of LPP presenting in the 
zosteriform pattern.

Leonforte JL, Pelaez de di Bari O 
Erythema dyschromicum perstans and lichen planus have been regarded as 
related. We describe the case of a 41 year old man presenting a relapsing 
dermatitis consisting of erythematous patches leaving behind ashy-gray 
macules. The lesions of lichen planus were atypical and the ashy dermatosis 
was transient. The possibility that some cases of lichen planus lead to an 
erythema dyschromicum perstans is discussed.

A 29-year-old woman from Trinidad experienced the rapid onset of extensive 
lesions characteristic of erythema dyschromicum perstans following an x-ray 
study using orally administered contrast. Eleven months later a skin biopsy 
specimen showed few epidermal changes but extensive incontinence of melanin 
pigment and marked dilatation of lymphatics in the superficial dermis. 
Results of a systemic evaluation were normal. The available data on this 
disease are analyzed and conclusions offered regarding its nature and causes.

Tschen JA, Tschen EA, McGavran MH 
Erythema dyschromicum perstans (EDP) was first described in 1957, and 
electron microscopic studies were reported in 1969. Herein, we describe 
five cases and compare light and electron microscopic findings, direct and 
indirect immunofluorescence, and dopa-positive melanocyte counts between 
normal and affected skin. The results indicate that EDP is a clinically 
characteristic disorder with a lichenoid reaction in its active phase. This 
lichenoid reaction leads to a pronounced incontinence of pigment and to 
decreased numbers of melanocytes and of tyrosinase activity in the involved 
epidermis. These findings support the suggestion that EDP and lichen planus 
pigmentosus are possible the same entity. Direct inmunofluorescence and 
fine structural studies show similar findings to lichen plunus. Patients 
have low-titer antibodies to extranuclear basal cell components.

The authors report a case of Erythema Cinitiensis Perstans, in a thirty-one 
years old white man. This dermatosis, reported in the literature also es 
Ashy Dermatitis and Erythema Dyschromicum Perstans, is here in Brazil 
exceptional. Clinically this dermatosis is characterized by the presence of 
gray patches in a sometimes surrounded by an erythematous active border. 
The lesions may occur on any area of the integument, sparing the hair 
scalp, palms, soles and nails. The therapy has been ineffective in all the 
cases, but one reported by Stevenson and Miura and in our case, where the 
patients have improved after Dithiazanine iodide treatment due to 
intestinal parasitoses by the Tricocephalus trichiurus.

Degos R, Civatte J, Belaich S 
The feeling of the authors is that their seven reported cases of a 
pigmented dermatosis are different from the ashy dermatosis and from the 
erythema dyschromicum perstans. This disease, which affects children and 
teenagers, males as well as females, is characterized by pigmented macules 
5-25 mm in diameter, affecting the neck, the trunk and the limbs. The first 
symptom is whether a pigmented spot, or an erythematous, papular or 
achromic lesion; in the latter instance the pigmentation occurs only 
secundarily. In most of the cases this dermatose is slowly and 
spontaneously regressive. The histological picture is not really specific. 
In one case there was a marked intraepidermal dyskeratosis of the sweat 
duct openings. The etiology remains unknown.

Four patients with ashy dermatosis are described. Their ages varied from 8 
to 12 years. Three had typical widespread macular eruptions and one had a 
linear lesion not described before. The follow-up investigation revealed 
that the eruption disappeared within 2 years in three of the patients. One 
patient could not be followed. The duration of the disease and the 
linearity of one lesion resembled lichen ruber planus.

================================================================= 
Dermatologica 1975;150(5):287-91 

Jablonska S 
Clinically and histologically typical erythema dyschromicum perstans has 
been provoked by repeated ingestion of very small amounts of a fertilizer, 
ammonium nitrate. It has been used by a boy who has noticed accidentally 
that after licking the fertilizer he developed hyperpigmentations. His main 
purpose was to avoid school attendance, and he developed a very ingenious 
method of licking the fertilizer once in several weeks in such a way that 
it did not produce any digestive or other troubles. His brother, an 
uniovular twin who had no contact with ammonium nitrate, was healthy. The 
case supports Pinkus' hypothesis that this type of lesions may be related 
to some environmental contaminant. Attention is called to a possible food 
contamination by ammonium nitrate.

Clinical, histological and ultrastructural investigations of two cases of 
Erythema Dischromicum Perstans (EDP) are reported. EDP is a chronic 
pigmented lesion of the skin, and its etiology is still unknown. The 
reported cases showed clinical and ultrastructural differences from what 
already described in the literature. EDP is also difficult to differentiate 
from other cutaneous pigmented lesions: clinical and morphologic 
differences and/or similarities are therefore discussed and compared. The 
usefulness for a correct diagnosis of the co-existence of optical and 
ultrastructural lesions which are not pathognomonic per se, is also stressed.

Five patients with ashy dermatitis are described, aged 6 to 14, one boy and 
four girls. The process is characterized by dirty grayish or 
ash-gray-colored maculae on the skin of the trunk and limbs. These maculae 
do not tend to fuse, nor exfoliate; they are not associated with any 
subjective sensations. Thorough examinations have not revealed any 
osteomuscular or visceral abnormalities. The disease runs a benign course, 
and only the cosmetic defect worries the patients.

The authors make a review of the epidemiologic, etiopathogenic, clinical, 
laboratory and therapeutic aspects of ashy dermatosis, described in 1957 by 
Ramirez in El Salvador, of which more than 150 cases have been described up 
to now in different continents. The disease is exclusively cutaneous, 
presents peculiar clinical features with a lichenoid tissue reaction, and 
has no specific treatment or known etiology. The authors report a case in a 
Brasilian man, followed up for three years. The treatment of a T. trichiura 
infestation did not change the cutaneous features, as opposed to what has 
been reported.

During the period between january 1984 to july 1987 in the Hospital Unit 
"Presidente Juarez" ISSSTE, Oaxaca (Mexico), for the first time was given 
dermatology consult to 2,683 patients among them, 23 who had ashy 
dermatosis (Erithema dyschromicum perstans), a study was done for the 
present time and the future of the same, discarding it as possible cause of 
that nosological entity: treponemal disease, parasitic, infectious, hepatic 
and renal. It is commented in relation with the ashy dermatosis and lichen 
planus, the clinicals variants and the possible sun etiology.

Besides the inherited forms of mottled and reticulate pigmentation, a vast 
number of diseases and trigger mechanisms can lead to acquired pigmentation 
of the neck. Nonhereditary variants of reticulate and mottled pigmentation 
can affect the neck as a typical site and therefore may give a diagnostic 
clue or it can occur sporadically on the neck as well as on other sites. A 
well-known and important factor in the pathogenesis is exposure to 
sunlight. Sun-induced pigmentation often presents on the neck and may 
result from phototoxic, photoallergic and cumulative actinic damage. 
Frequent forms comprise berloque dermatitis, Riehl's melanosis, 
poikiloderma of Civatte and tanning bed lentigines. Different infections 
may also lead to this distinct skin alteration as pediculosis capitis, 
pityriasis versicolor and syphilis II. Treatment-induced irregular 
pigmentations may occur after applications of topical agents (e.g. 
diphenylcyclopropenone), systemic medication (e.g. 5-fluorouracil, 
chlorpromazine), as a complication of laser resurfacing or as a chronic 
graft-versus-host reaction. Different neoplasms may also involve the neck. 
Widespread pigmented basal cell carcinoma, cutaneous T-cell lymphoma, 
syringolymphoid hyperplasia and histiocytic diseases may lead to 
reticulated pigmentation. Various other infrequent conditions as connective 
tissue diseases, malnutrition, lichen planus pigmentosus and others are 
summarized. The neck, a readily accessible site to medical inspection, may 
have an underestimated value for the diagnosis of different skin diseases.

associated, related to a head and neck carcinoma. Both cutaneous conditions 
disappeared after treatment of the neoplasia. Diagnostic criteria of lichen 
planus pigmentosus are reviewed. The paraneoplastic nature of this original 
observation of lichen planus pigmentosus is discussed.

We report on a 21-year-old man professionally exposed to mercury, who 
developed lichen planus. This case must be regarded as a dispositional 
reaction and is in Germany entitled to indemnification in terms of a 
"quasi-occupational disease". The clinical signs and the probably 
non-allergic pathomechanism are comparable with those of lichen planus 
induced by gold. In diseases due to occupational intoxication, we face an 
individual disposition regarding the degree of clinical symptoms, which has 
to underly any expert opinion on indemnity.
