Bullous dyskeratosis follicularis and acrokeratosis verruciformis. Report of a case

Morbus Darier, Hailey's familiar benign chronic pemphigus, and acrokeratosis verruciformis were observed in one patient. The diagnosis was based on the clinical picture and microscopic studies. The simultaneous occurrence in one patient of these congenital diseases suggests that it is possible that all three disorders are variants of one and the same disease. Five close relatives of the patient had acrokeratosis verruciformis.
