Abstract
A 58-year old woman was admitted to our hospital complaining of abdominal distension, leg edema and 10 kg weight increase for a month. Abdominal ultrasonography, computed tomography (CT) and magnetic resonance imaging (MRI) revealed a heterogeneous giant tumor in the abdomen. Angiography showed some hypervascular lesions supplied by the gastroepiploic arteries. An operation was performed under the diagnosis of an omental malignant tumor. The tumor, which originated from the greater omentum, was resected with a block of the greater omentum. The resected tumor measured 32×26×13cm and weighed about 6, 900g. The histopathological diagnosis was mixed type liposarcoma (myxoid type and round cell type). Three months after the operation, local recurrence was detected. We performed a second operation, but found extensive peritoneal dissemination. About one month later the patient dead.
