TRICHOSTASIS SPINULOSA

Abstract

History.—S. T., aged 56, of Jewish extraction, a butcher, born in Russia, presented himself at the department of dermatology at the Montreal General Hospital in September, 1930, on account of an eczema, erythematosquamous and slightly exudative in character, over the right leg, thighs, abdomen and back. The condition began in June, 1930; it was characterized by considerable pruritus and had not yielded to treatment. The patient was admitted to the hospital, and he gradually responded to local and general treatment. No further mention need be made of this condition. While he was in the hospital, attention was directed to a very peculiar condition of his hair, a condition of which the patient was totally unaware. He was a well built man, of a swarthy, somewhat sallow type. His hair was turning gray, and he presented a hippocratic type of baldness, with the vertex quite bald. Numerous
