“…İlaçlar-dan ise etambutolun nadiren likenoid ve EDP benzeri erüpsiyona neden olduğu bildirilmiştir (5). EDP'nin liken planusun bir varyantı olduğu düşünülmekle birlikte, liken planustan önce ve sonra gelişen EDP olguları bildirildiği için her iki hastalığın ilişkili ayrı antiteler olabileceği öne sürülmüştür (6,7).

“…Flexural involvement including the axilla (8.9%), inframammary folds (6.5%), and groin (3.2%) was seen less frequently. Vega et al 8 published a clinicopathologic study of 11 cases of LPP describing distributions primarily in the face (73%) and trunk (45%). The axillary and inguinal folds were only affected in two patients.…”

“…In the past, ashy dermatosis was thought to be the same condition as LPP. However, Vega et al 8 reported clinical differences between ashy dermatosis and LPP including the presence or absence of pruritis and lesion color. Pigmented contact dermatitis is a non-eczematous variant of contact dermatitis, character- ized clinically by hyperpigmentation caused by common allergens such as fragrances, preservatives and deodorants.…”

Lichen planus pigmentosus-inversus is a rare variant of lichen planus pigmentosus. The eruption of lichen planus pigmentosus-inversus occurs mainly in the flexural regions and presents with brownish macules and patches. Here we describe the case of a 31-year-old Korean woman who presented with hyperpigmented lesions over her antecubital and popliteal area and groin. Physical examination revealed multiple brownish macules and patches on the intertriginous area without pruritis, and histologic findings showed a regressive pattern of lichen planus. These clinical and histological findings were consistent with a diagnosis of lichen planus pigmentosus-inversus.

“…El liquen plano pigmentoso 32,43,44 afecta a ambos sexos y aparece entre la primera y la séptima década de vida, aunque en la mayor serie el 87% tenía entre 15 y 46 años 44 . Se presenta en forma de máculas azuladas o grisáceas, redondas u ovaladas pequeñas, mal definidas, en ocasiones confluentes, formando lesiones mayores; sus márgenes son irregulares y se atenúan hacia la periferia; afectan habitualmente la cara, frente y regiones preauriculares -casi siempre afectadas en forma inicial-, extremidades superiores, abdomen y parte alta de la espalda (céfalo-caudal).…”

ResumenLa dermatosis cenicienta es un trastorno pigmentario infrecuente que se presenta en individuos de piel morena, especialmente en centroamericanos. Las lesiones consisten en manchas hiperpigmentadas de coloración gris-azulada, principalmente localizadas en la cara, tronco y brazos. Su principal diagnóstico diferencial debe ser planteado con tres dermatosis pigmentarias de origen idiopático: eritema discrómico perstans, pigmentación macular eruptiva idiopática y liquen plano pigmentoso. Hay consenso en considerar al eritema discrómico perstans como la misma enfermedad, pero con un borde eritematoso transitorio. La pigmentación macular eruptiva idiopática es clínicamente similar, pero sin una dermatitis de interfase al estudio histopatológico, y sólo muestra una pigmentación de la capa basal, incontinencia pigmentaria y melanófagos en la dermis. Finalmente, el liquen plano pigmentoso debe ser considerado como una variedad pigmentada de liquen plano. Palabras clave: Dermatosis cenicienta; eritema discrómico perstans; liquen plano pigmentoso; pigmentación macular eruptiva idiopática summaRy Ashy dermatosis is an infrequent disorder of pigmentation, which predominantly occurs in darkly pigmented individuals, specially in central americans. The lesions consist of bluish-gray hyperpigmented patches mainly located on the face, trunk and arms. Its main differential diagnosis must be raised with three idiopathic pigmentary disorders: erythema dyschromicum perstans, idiopathic eruptive macular pigmentation and lichen planus pigmentosus. It has been widely accepted that erythema dischromicum perstans is the same disease, but with a transient erythematous border. Idiopathic eruptive macular pigmentation is clinically similar but without an interfase dermatitis at histopathologic studies, only showing increased pigmentation of the basal layer and pigmentary incontinence and many melanophages in the dermis. Finally, lichen planus pigmentosus must be considered as a pigmented variant of lichen planus. Key words: ashy dermatosis, erythema dyschromicum perstans, lichen planus pigmentosus, idiopathic eruptive macular pigmentation. aRtículo de RevisiónDermatosis cenicienta: revisión y diagnóstico diferencial con otros trastornos pigmentarios idiopáticos intRoducciónDescrita por Ramírez en el Salvador en 1957, la dermatosis cenicienta es una enfermedad relativamente infrecuente, de etiología desconocida, caracterizada por manchas de coloración grisácea, de tonalidad variable, localizadas especialmente en cara, tronco y brazos 1 . El tamaño de las lesiones varía entre máculas de 1 centíme-tro hasta manchas extensas, a las que en forma ocasional se les describe transitoriamente en su fase activa un borde eritematoso, o más raramente palpable 2 , por lo que es también conocida como eritema discrómico perstans, nombre ampliamente aceptado como sinónimo, aunque discutido y objetado por algunos autores 3 . La evolución del cuadro es hacia la cronicidad, con crecimiento de las lesiones y aparición de otras nuevas, formando a veces po...
