A.神經(jīng)鞘瘤來(lái)源于神經(jīng)鞘細(xì)胞，神經(jīng)纖維瘤來(lái)源于神經(jīng)束膜、外膜或內(nèi)膜等支持細(xì)胞
B.神經(jīng)鞘瘤最常見(jiàn)部位為正中神經(jīng)干、尺神經(jīng)干、坐骨神經(jīng)及橈神經(jīng)，神經(jīng)纖維瘤可發(fā)生于神經(jīng)末梢或神經(jīng)干的任何部位
C.神經(jīng)鞘瘤多為單發(fā)，神經(jīng)纖維瘤可單發(fā)或多發(fā)，以多發(fā)者為常見(jiàn)
D.神經(jīng)鞘瘤之神經(jīng)纖維穿過(guò)瘤體，神經(jīng)纖維瘤之神經(jīng)纖維并不穿過(guò)腫瘤組織
E.神經(jīng)鞘瘤可與神經(jīng)纖維完整分離，而切除神經(jīng)纖維瘤必須切斷神經(jīng)纖維
