The incidence of psoriasis among the population at large was calculated by Gahan1 at "not less than 1.0 per cent of the people living in and around New York." The basis for his figure was the fact that approximately 700 new cases of psoriasis were seen annually at the New York Skin and Cancer Unit. He estimated that "probably the Skin and Cancer Unit received no more than 10 per cent of the total number of patients who go for treatment to the various clinics in the New York Metropolitan Area," but he allowed, in arriving at a rough estimate, that even if that clinic received even as much as 20 per cent, "this would indicate a minimum figure of 100,000 for the number of persons suffering from psoriasis in and around the city of New York, an area containing approximately 10,000,000 population."
