胃平滑肌瘤和胃平滑肌肉瘤临床上很难鉴别,有时组织学检查确诊为良性,而病程经过所反应出的生物学特性又似恶性,给临床诊断和处理带来一定困难。我院1962年4月～1987年7月收治21例中经手术后病理证实、资料完整的19例作一回顾性探讨,以找其共性、差异和联系之所在。 Gastric leiomyosarcoma and gastric leiomyosarcoma are difficult to distinguish clinically, and sometimes histological examination is confirmed as benign, and the biological characteristics reflected by the disease course are also considered to be malignant, which brings certain difficulties for clinical diagnosis and treatment. In our hospital from April 1962 to July 1987, 21 cases of 19 postoperative pathologically confirmed and complete data were reviewed retrospectively to find out their commonalities, differences, and connections.
