血管内皮细胞瘤是一种发病率极低、低度恶性的血管来源肿瘤,生物学特性介于血管瘤和血管肉瘤之间,很少发生远处转移。临床症状以局限性疼痛和软组织肿胀为最常见。组织学表现为非典型的内皮细胞过度增殖,细胞核呈圆形或短梭形,染色质增多,核仁易见,胞浆较丰富,淡染或呈细颗粒状,细胞异型性明显,核分 Vascular endothelial cell tumor is a very low incidence of low-grade vascular tumors, the biological characteristics between hemangiomas and angiosarcomas, rarely distant metastasis. Clinical symptoms are most common with localized pain and soft tissue swelling. Histology showed atypical endothelial cell hyperproliferation, the nucleus was round or short fusiform, increased chromatin, nucleolus easy to see, the cytoplasm is more abundant, lightly stained or fine granular, cell atypia is obvious, nuclear
