Malignant Reticuloendothelioma. Presented by Dr. Irving Bancroft and Dr. Joseph Mirovich (by invitation).
L. M., a 69 year old white housewife, had no eruption until eight or nine months ago, when she noticed a purplish spot on the right leg just above the ankle. This lesion enlarged peripherally, and later several new lesions appeared in a line toward the groin. There is now a confluent mass of tumors covering the lower part of the right leg. This has been formed by bright red patches which have become tumors, gradually enlarging to become confluent. The mass thus formed is bright red, warm to the touch, nontender and nonpruritic.The results of examination of the blood were as follows: The Wassermann and Kahn reactions were negative. The nonprotein nitrogen content was 45 mg. and the iodine content 4.9 micrograms per hundred cubic centimeters. Tests showed no bromine. The hemoglobin content was 94
