[Liposarcoma of the gallbladder and the peritoneum. A case report].

We report a case of a male patient who was cholecystectomized at the age of 79. We diagnosed an intramural myxoid liposarcoma of the gall bladder without signs of metastasis. Two years later at autopsy we found a diffuse spread of the same type of tumour on mesentery, omentum maius, parietal and visceral peritoneum. The unusual primary site of the tumour is pointed out referring to literature, the question of primary multicentric liposarcoma resp. diffuse peritoneal metastases is discussed.
