A 22-year-old negroid man complained of a skin eruption which had been present for two years. The initial lesions were minute papules confined to the pectoral regions; later they had spread to the trunk, shoulders, and extremities. They were numerous round to oval papulosquamous lesions, 0.5 to 2.0 mm. in size. They were absent in the axillae, in the groin, and on the scalp, palms, and soles. Around the neck and upper chest they were confluent and reticulated. There were many glistening minute papules on the hard palate. There were keratotic follicles on the extensor surfaces of all extremities. The dermatosis described was the only physical abnormality in an otherwise healthy man.
