Abstract

Psoriasis is relatively common among cutaneous diseases. Many general statements concerning it appear in the various dermatologic texts, but there is little statistical evidence in regard to this disease. Schamberg1 in 1924 supplied some definite data on a large group of cases but gave information only in regard to the age and sex of the patient, the age at onset and the familial incidence. Aside from this contribution there are in the main only general impressions gathered from small series of cases, and detailed figures in support of the statements made are lacking. The cases of psoriasis observed in the last few years at the dermatologic clinic of the Massachusetts General Hospital have been studied with a view to supplying more definite evidence concerning these impressions. For the sake of brevity the data will be presented as far as possible in tabular form.
