血管球瘤(glomus tumor)是由正常血管球小体中修饰的平滑肌细胞非常类似的细胞构成的间叶性肿瘤,血管球细胞由Rouget在1873年首先报道,是位于球状动静脉吻合管壁周围的一种变异的平滑肌细胞,分布于全身各处,以甲床、指(趾)侧面和手掌最多见,也可发生在尾骨前[1]。血管球瘤由Masson1924年首次报道,被认为是动脉与静脉吻合处的血管球形成的良性肿瘤,其瘤体是一种特殊化的平滑 Glomus tumor is a mesenchymal tumor composed of cells that are very similar to smooth muscle cells modified in normal glomerular bodies, first reported by Rouget in 1873 and located around the wall of an anastomotic ball-shaped anastomosis A variant of smooth muscle cells, distributed throughout the body to nail bed, finger and toe side of the palm of the most common, can also occur in the coccygeal [1]. Glomus tumor, first reported by Masson in 1924, is considered to be a benign tumor of the blood vessels formed by the anastomosis of arteries and veins. The tumor is a kind of special smooth
