平滑肌肿瘤分为良性、恶性及介于二者之间的平滑肌母细胞瘤。由于临床并不多见,为探讨其诊治经验,现将我院1973～1993年经手术病理证实的47例报道如下: 1 临床资料 本组共有消化道平滑肌肿瘤47例,其中平滑肌瘤44例,平滑肌肉瘤3例;男30例,女17例;年龄18～78岁,≤30岁2例,31～69岁37例,≥70岁8例。肿块直径1.5cm～16cm。 食道平滑肌瘤2例,占4.2％。病史分别为2个月及6年,均表现为进食梗阻感,但无消瘦。1例术前食道吞钡检查误诊为食道癌,胃镜检查两例均符合平滑肌瘤,手术切除肿块及部分食道,预后良好。 Smooth muscle tumors are divided into benign, malignant and smooth myoblastomas.
