An unusual case of primary mucinous carcinoma of the skin has been reported. The tumor progressed very rapidly and recurred twice within a short period after adequate local excision. It had wide spread lymph node metastases and a fatal ending. The characteristic clinical and histologic differentiation from sweat gland carcinoma has been discussed.

A case of retroperitoneal cystic lymphangioma is reported. Added to the 42 cases of retroperitoneal lymphangioma found from the English literature, this brings up the total of cases reported to date to 43. A critical review of the clinical picture and management of this condition is presented on the basis of these reported cases.

Ethanol (0.4 to 0.8 g/kg in 30 minutes) was given by mouth to 102 healthy young volunteers (37 Caucasian men, 21 Caucasian women, 20 Chinese men and 24 Ojibwa men). Venous blood concentrations of ethanol and acetaldehyde 60, 90, 120 and 150 minutes after the end of drinking were measured by gas chromatography. The calculated rates of ethanol metabolism in the Caucasian men and women did not differ, but the overall group means for subgroups of Caucasians (103.6 mg/kg-h), Chinese (136.6 mg/kg-h) and Ojibwa (182.7 mg/kg-h) with decreasing postabsorption values differed significantly from each other. Mean acetaldehyde values paralleled the rates of ethanol metabolism: Ojibwa, 14.6 mug/ml; Chinese, 10.0 mug/ml; and Caucasians, 9.4 mug/ml. The high rate of ethanol metabolism in Amerind subjects differs from previous findings. Habitual level of alcohol consumption, proportion of body fat and genetic factors appear to account for most of the group differences.
