【摘要】 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。更多还原

【Abstract】 This paper included 30 cases of glomus turners. Eighty percent of the tumors were locatd under the nails of fingers. Pain was the important symptom of these patients, Histologically, these tumor cells were round or polygonal in shape and surrounded the small vessels. These cells had large nuclei, abundant and clear cytoplasm. Sometimes, myxoid degeneration could be found in some area of tumors. Ultrastructurally, the tumor cells were invested by a continuous basal lamina-like structure. Abundant filaments. dense body and the attachment plates, like that from smooth muscle cells, were found in the cytoplasms.It is suggested that glomus tumor originates from vascular smooth muscle. There were nerve endings on the Capsule of the tumors.更多还原
