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.
作者报告了一例恶性胃平滑肌瘤（上皮样平滑肌肉瘤），该病例曾被误诊为胰腺假性囊肿。患者在另一家医院接受了多次手术。其中一次手术进行了囊肿胃造口术。1989年11月，当我们再次为该患者手术时，发现一个源于胃后壁的巨大肿瘤块。组织病理学诊断为胃平滑肌瘤。得出的结论是，胰腺囊性病变的壁应始终进行组织学检查，以排除恶性肿瘤的可能性。
