以下是引用xhyong在2011-2-15 21:55:00的发言: 转帖一段话:Occasional angiosarcomas show predominantly spindled features and can be confused with SCH(spindle cell angioma). Again, careful attention to the absence of circumscription and the presence of diffusely infiltrating growth should point one toward the correct diagnosis. Most spindled angiosarcomas show focal areas of typical angiosarcoma, characterized by more epithelioid cells forming primitive vascular channels. Angiosarcomas also show significant nuclear atypia, frequent mitoses, and will often have foci of necrosis, all features typically absent in SCH. |
谢谢Drxhyong!
英文大意如下:
血管肉瘤偶尔表现出以梭形细胞为主的形态,这可能会被误认为是梭形细胞血管瘤(SCH)。仔细观察是否存在弥漫性浸润性生长,依此,则有利于确诊。多数梭形细胞性血管肉瘤总会见到局灶区有经典的血管肉瘤成分,其特点为:由较多的上皮样细胞构成原始血管腔隙。血管肉瘤还显示明显的核异型,易见核分裂,并常可见坏死灶。而所有这些特点在SCH是不会照例出现的。
