Palmar and finger prints were obtained in patients with acantholytic dyskeratotic dermatoses. Identical patterns were found with Darier's disease, Grover's disease, Galli-Galli disease, acrokeratosis verruciformis of Hopf, and warty dyskeratoma. Because dermatoglyphic patterns are a genetically determined individual characteristic, we propose that acantholytic dyskeratotic dermatoses with identical dermatoglyphic patterns are variable manifestations of a single disorder, despite their broad spectrum of clinical manifestations.
