Xanthoma Tuberosum. Presented by Dr. Carroll S. Wright and (by invitation) Dr. L. Jaffe.
R. H., a white youth aged 18, well nourished and well developed, presents two soft, salmon-colored nodules, each about 1 in. in diameter, one on the extensor surface of each elbow. There is one flat, salmon-colored macule about 4 mm. in diameter on the web between the left thumb and index finger. These had their onset when the patient was 10 yr. of age. The initial lesions were the size of small peas, and were mistaken for warts. They have gradually grown to their present size. The patient was on a diet rich in dairy products and eggs, including ice cream every night and eggnog every morning, for many years. A maternal aunt has "heart trouble," the patient's twin sister, "thyroid trouble." There is no family history of cutaneous diseases.Blood count and urinalysis results
