间叶性软骨肉瘤极为少见,发生在软组织内的更为罕见。1975～1985年,我们在外检工作中遇到二例发生在软组织内的间叶性软骨肉瘤,报告如下,并着重对软组织内与其易混淆的几种肿瘤的鉴别诊断作一些探讨。【临床病例】例1 男性,16岁,因面颊部膨降4～5个月住院。体检发现右面颊部隆起,以硬腭处膨出更为明显,鼻右侧壁变形。术中见近右上颌窦软组织处有一4×4cm左右境界不清之肿块,表面呈颗粒状,触之易出血。
Mesenchymal chondrosarcoma is extremely rare and occurs more rarely in soft tissue. From 1975 to 1985, we encountered two cases of mesenchymal chondrosarcoma in soft tissue during the inspection. The report is as follows, and some discussions are made on the differential diagnosis of several kinds of tumors which are easily confused with each other in soft tissue. [Clinical cases] Example 1 male, 16 years old, due to the reduction in the cheek 4 to 5 months hospitalization. Physical examination found that the right cheek bump to the hard palate bulging more obvious deformation of the right nasal wall. Surgery, see near the right maxillary sinus soft tissue at a 4 × 4cm unclear tumor around the surface was granular, easy to touch the bleeding.
