Dermatosis papular acantolítica de la vulva con buena respuesta a tacrólimus tópico.

Papular acantholytic dermatosis of the vulva is a rare, chronic disorder and is an entity that remains to be fully understood.

The lesions consisted of whitish papules and erosions on the labia majora. Histologically, there was hyperkeratosis and focal parakeratosis with acantholytic and dyskeratotic cells. She did not respond completely to topical steroids but clinical improvement occurred after the use of topical tacrolimus.
