[Verrucous carcinoma of the penis arising from a lichen planus. A true preneoplastic lesion?]. / Carcinoma verrucoso de pene desarrollado sobre un liquen plano. Una auténtica lesión preneoplásica?

INTRODUCTION: Up to 30% of squamous cell carcinomas of the penis arise from a lichen sclerosus, but very few reports in which lichen planus was the preexisting lesion have been published. We report a male with verrucous carcinoma of penis that developed in an area of lichen planus. CLINICAL CASE: A 53-year-old male presented with an exophytic tumor on the glans penis that had been present for about 6 months. The lesion developed in a previously biopsied area of lichen planus hypertrophicus. After excision, histological diagnosis was verrucous carcinoma. COMMENT: The development of any subtype of squamous cell carcinoma of penis in a lichen planus can be coincidental, or a neoplastic transformation of lichen planus can take place.

Carcinoma verrucoso de pene desarrollado sobre un liquen plano. ¿una auténtica lesión preneoplásica? / Verrucous carcinoma of the penis arising from a lichen planus. A true preneoplastic lesion?

Introducción: Hasta un 30% de carcinomas epidermoides de pene se desarrollan sobre un liquen escleroso, mientras que hay muy pocos casos publicados en los que la lesión preexistente sea un liquen plano. Se presenta un carcinoma verrucoso de pene desarrollado sobre un área de liquen plano. Caso clínico: Un varón de 53 años consultó por presentar un tumor exofítico en glande de 6 meses de evolución, que había crecido sobre una lesión biopsiada 2 años antes, y diagnosticada como liquen plano hipertrófico. Tras su extirpación, el diagnóstico histológico fue de carcinoma verrucoso. Comentario: el desarrollo de cualquier variante de carcinoma epidermoide de pene sobre un liquen plano puede ser meramente casual, o por el contrario podría ser una transformación neoplásica del mismo
