Porphyria Cutanea Tarda. Psoriasis. Presented by Dr. Otto C. Stegmaier.
History: A 44-year-old white man was first seen on May 6, 1958, because of a chronic scaling dermatitis of the scalp. At that time it was noticed that he had a purplish pink color of the face and "V" of the neck.

He is a bartender.
