[Gastric epithelioid leiomyosarcoma simulating pancreatic pseudocyst. Report of a case and review of the literature].
The authors report a case of malignant gastric leiomyoblastoma (epithelioid leiomyosarcoma) which was mistaken for a pseudocyst of the pancreas. The patient was operated several times in another hospital. At one of the operations a cystogastrostomy was performed. In november, 1989, when operated again by us, a large tumoral mass arising from the posterior gastric wall was found. The histopathological diagnosis was leiomyoblastoma of the stomach. It is concluded that the wall of a pancreatic cystic lesion should always be submitted to histologic examination in order to be excluded the possibility of a malignant neoplasm.
