Painful white plaques of the folds revealing papular acantholytic dyskeratosis

Abstract

Papular acantholytic dyskeratosis (PAD) is a challenging diagnosis for both dermatologist and pathologist. It predominantly affects female patients, but men can present less frequently the disease. Histopathology is required to confirm the diagnosis and to exclude other acantholytic dermatoses. We present a rare case of PAD in a young male patient, diagnosed by histopathology, and responded well to oral retinoids.
