A CASE OF GREATER OMENTAL SARCOMA WITH HYPOGLYCEMIA

Abstract

A 75-year-old man was admitted to the hospital because of hypoglycemia and an abdominal mass. The patient was diagnosed as having a greater omental tumor with liver metastasis by various examinations, and was operated on. Pathologically, the tumor was poorly differentiated sarcoma originated from the greater omentum with liver metastasis. The patient died of prominent peritoneal dissemination 17 months after the operation. Sixty cases including our case of malignant tumor origniated from the greater ometum have been reported in the past 16 years in Japan. Angiography was useful examination for the diagnosis of these tumors, and peritoneal dissemination occurred in 44.1% of those 60 cases.
In our case, serum IGF-II and other endocrinological factors were all within normal limits. However, since IGF-II in the tumor cells was not measured, a possibility that IGF-II had caused hypoglycemia is not completely excluded.
