Cutaneous Horn and Epithelioma. Presented by Dr. David. L. Satenstein.
An Italian woman, aged 76, about six months ago noticed a small nodule on the vermilion border of the lower lip. It caused no subjective symptoms but gradually increased in size. She received no treatment. The conical lesion extends outward from the vermilion border about 1½ inches (3.77 cm.). It is sharply margined, and dull gray at its tip, which is elevated 1 inch (2.5 cm.). The base is surrounded at its border by an excoriated zone. There is little infiltration of the lip, and there are no palpable lymph nodes anywhere. The patient is from the clinic for diseases of the skin of the New York Post-Graduate Medical School and Hospital.
Dr. Ludwig Oulmann: There is no doubt that the diagnosis is correct. These cases easily develop into cancer, although there is no sign of a malignant process
