Abdominal form of lymphomatoid granulomatosis.

A 54 year old white male died three months after hospitalization for hematemesis and melena due to a duodenal ulcer and two monthos after the subsequent onset of progressive ascites and edema. At necropsy, lesions characteristic of "lympomatoid granulomatosis" as delineated by Liebow et al. were found in the liver, retroperitoneal lymph nodes, and mesenteric and retroperitoneal adipose tissue. This case appears to be the first case of "lymphomatoid granulomatosis" confined to the abdomen. This report further broadens the clinical spectrum of the newly delineated "lymphomatoid granulomatosis" and adds another situation to the differential diagnosis of space occupying lesions of the liver.
