A Case for Diagnosis. Presented by Dr. B. L. Kahn.  This man, aged 51, presents over the posterior aspect of the neck a large circumscribed, indolent ulcer with a slightly raised border. The base is clean and granulating, with some serous discharge. There is no tenderness. On both legs, extending from the knee to the ankle, are numerous discrete, raised, rounded, dark-crusted lesions. On the hands there are similar lesions, with several depressed, pigmented scars.The lesion on the neck first appeared in 1923 and subsequently healed following roentgen therapy. It reappeared in May 1932, but at that time irradiation was ineffectual. The lesions on the legs appeared about one and one-half years ago. A roentgenogram of the chest revealed no evidence of tuberculosis and only a dilatation of the ascending aorta. There is mild secondary anemia. The reaction to the Kahn test was negative.
