Xanthoma Tuberosum. Presented by Dr. Klauder.
P. D., aged 48, an Italian laborer, had had a mass on the forehead for two months. It appeared spontaneously. The Wassermann reaction was negative. There had been no blood chemistry examination. The general health was good. This mass was roughly the size of an English walnut, reddish and showed central ulcerations.
Dr. Weidman: I think the mass is malignant, possibly endothelioma. The fibrosarcomas undergo a xanthosis, and have been mistaken for a genuine xanthoma tuberosum.Dr. Munson: I agree with Dr. Weidman.Dr. Stokes: It certainly looks fibrosarcoma. I recommend biopsy as the only certain means of diagnosis.
Histologic studies have since shown that this lesion was a prickle cell carcinoma.
