A Case for Diagnosis (Leprosy? Sarcoid?). Presented by Dr. N. N. Epstein.
K. T., a Chinese man aged 53, reported to the University of California dermatologic clinic on April 15, 1941, with a well defined dark red plaque of five months' duration on the left cheek. He had been examined at the University of Chicago early in 1941. Wassermann and Kahn tests of the blood there had given negative results. Histologic changes observed in two successive biopsies had not been considered diagnostic.Examination reveals a dusky red plaque, measuring 5 by 10 cm., with a well defined, slightly irregular, sharply raised border. The lesion covers most of the left cheek. Inferior to this, situated on the neck, is another plaque, measuring 3 by 3 cm. A cordlike mass extends from the lower border of the larger plaque down the neck to a point just above the clavicle. Sensations of touch
