Familial benign chronic pemphigus.

In connection with three of eight recent cases of familial benign chronic pemphigus (FBCP) a brief review of its clinical, immunofluorescent, microscopic, and ultramicroscopic characteristics was made, with special emphasis on the differential diagnosis. The two main clinical aspects of the disease are emphasized: the moist, macerated, and intertriginous (candidiasis-like) variety, and the polycyclic plaque, with active and lichenoid edges (tinea corporis-like). Treatment was only partially successful, but slightly more effective with the lichenoid form of disease.
