Two cases of plexiform tumor of the uterus are presented. Both were incidental microscopic findings in leiomyomatous uteri and had the typical branching cords of small, polygonal cells with scanty cytoplasm and vesicular nuclei. Ultrastructurally the cells had features of smooth muscle differentiation such as actin-like filaments, dense bodies, peripheral dense plaques, pinocytotic vesicles, and incomplete basal lamina. Their close relationship to capillaries resembled the structure of glomus tumor and vascular leiomyoma and suggested histogenetic kinship among these neoplasms.
本文报告两例子宫丛状肿瘤。两例均为平滑肌瘤子宫中的偶然显微镜下发现，具有典型的由小的多边形细胞组成的分支索，这些细胞胞质稀少，核呈泡状。超微结构上，细胞具有平滑肌分化的特征，如肌动蛋白样细丝、致密体、周边致密斑、吞饮小泡和不完整的基膜。它们与毛细血管的密切关系类似于血管球瘤和血管平滑肌瘤的结构，提示这些肿瘤之间存在组织发生学上的亲缘关系。
