A multifocal leiomyosarcoma of the stomach originating from the muscularis mucosae with lymph node and distant metastases is described in a 66 year old man. The electron microscopic features of a representative tumor mass and a metastasis confirmed the smooth muscle histogenesis. The light microscopic appearance consistently suggested malignant fibrous histocytoma. The pathological features of gasttric leiomyosarcomas are reviewed with special emphasis on the problem of practical diagnosis. This case also indicates that not all sarcomas with storiform features are necessarily histiocytic in origin.
本文报道了一名66岁男性患者，其胃多灶性平滑肌肉瘤起源于黏膜肌层，并伴有淋巴结和远处转移。对一个代表性肿瘤块和转移灶进行的电镜检查结果证实了其平滑肌组织来源。光镜下表现始终提示为恶性纤维组织细胞瘤。本文回顾了胃平滑肌肉瘤的病理特征，并特别强调了实际诊断中的问题。该病例还表明，并非所有具有席纹状特征的肉瘤都一定起源于组织细胞。
