In 1950, Semetena and Bernhard1reported 14 cases of subcutaneous lipogranuloma; they used the term "sclerosing lipogranuloma" as a descriptive name. They felt that these cases, in which the process was localized and frequently followed trauma, could be separated from other recognized entities, such as Weber-Christian disease, traumatic fat necrosis of the female breast, adiponecrosis subcutanea neonatorum, and changes in the lung following aspirations of oils and fats. This separation was accomplished by showing differences in clinical features of the diseases and occasionally by histological features in the tissues. Spencer,2in 1949, described a case of "fat necrosis" of the omentum that followed a blunt injury to the abdomen. In this patient, there was a mass in the left lower quadrant simulating carcinoma of the colon. This mass was resected and was similar histologically to the lesions described by Smetana and Bernhard.1The lesion did not recur.
