本文总结30例血管球瘤,80%生长在手指部甲下。临床以疼痛为主,肿瘤细胞为圆或多角形,绕血管分布,细胞核大,胞浆宽广透明,形态均匀一致,常有粘液变。电镜下,细胞周围绕以基膜样物质,胞质内有丰富的微丝,致密体及相似于平滑肌细胞内的附着板。推测血管球瘤来自血管周围的平滑肌。此外,肿瘤包膜上有许多神经末梢,此与致痛有关。 This article summarizes 30 cases of glomus tumors, 80% growth in the finger under a. The main clinical pain, tumor cells are round or polygonal, around the blood vessels, large nuclei, cytoplasm broad and transparent, uniform form, often mucus change. Under electron microscopy, cells around the basement membrane-like substance, the cytoplasm is rich in microfilaments, dense body and similar to the smooth muscle cells within the attachment plate. Speculated glomerular tumors from the perivascular smooth muscle. In addition, there are many nerve endings on the tumor capsule, which is related to pain.
