RESUMO

ABSTRACT: Hypertrophic and acneiform forms are very rare variants of discoid lupus erythematosus (DLE), which can suppose a diagnostic and therapeutic challenge. We present a South American woman with facial disfiguring lesions of 7 years of evolution with clinical and histopathological characteristic of both hypertrophic and acneiform DLE. No criteria for systemic lupus erythematosus were present in the patient. To the best of our knowledge, no patients with concomitant hypertrophic and acneiform DLE have been previously reported in the literature.

RESUMO

Lichen aureus is a rare pigmented purpuric dermatosis. We present an unusual case because of the pediatric age and the great number of lesions with zosteriform distribution. He is a 10-yearold boy, with a brownish, smaller than 1 cm, sharp edges, lichenified surface, asymptomatic macule, over the inner aspect of the left leg with a zosteriform distribution. The histology showed a band-like inflammatory infiltrate in the superficial dermis, composed of lymphocytes, histiocytes, erythrocytes and haemosiderin. He was diagnosed with zosteriform lichen aureus and was treated with topical mometasone furoate during 3 weeks resulting in partial lightening of the macules. Lesions have remained 2 years later, and new ones have appeared in the ipsilateral ankle. We must consider differential diagnosis with other pigmented purpuric dermatitis and pigmented purpuric mycosis fungoides. There are many therapeutic options and it tends to disappear spontaneously, so new studies are necessary.


El liquen aureus es una dermatosis purpúrica pigmentaria infrecuente. Presentamos un caso inusual por su edad pediátrica y por la presencia de lesiones múltiples con patrón zosteriforme. Se trata de un niño de 10 años con máculas parduzcas, menores de 1 cm, con bordes definidos y superficie liquenificada, en la cara interna de la pierna izquierda con distribución zosteriforme, asintomáticas, de tres meses de evolución. La biopsia mostró infiltrado en banda en la dermis superior con linfocitos, histiocitos, hematíes y hemosiderina. Se diagnosticó liquen aureus zosteriforme y se trató con furoato de mometasona tópico durante 3 semanas con aclaramiento parcial. Las lesiones permanecen 2 años después y han aparecido nuevas en el tobillo ipsilateral. Debemos plantearnos el diagnóstico diferencial con otras dermatosis purpúricas pigmentarias crónicas y la variante purpúrica pigmentaria de la micosis fungoide. Existen muchas opciones terapéuticas e, incluso sin tratamiento, suelen desaparecer, por lo que son necesarios estudios que recopilen más evidencias.
