[An inverse course of Darier dyskeratosis follicularis]

A 56-year-old female patient had suffered from isolated, unclassified palmoplantar keratosis since childhood. During the climacteric horny papules appeared for the first time on the extremities and trunk. Histologically, the efflorescences on the body and the palmoplantar keratosis were classifiable as keratosis follicularis. Predilection sites of Darier's disease were spared. Altogether, the usual pattern of involvement was reversed.
