摘要
对10例子宫腺瘤样癌作临床病理分析后发现,2例处于早期形成阶段,为探讨其组织起源提供了形态学依据。1例在主瘤以外的间质内有多处与主瘤不相连续的散在岛屿状病灶,其形态、组化反应与主瘤一致;另1例的巨检似有局限性集中的趋向,但镜下见病变分散在子宫肌层的间质内,尚未完全形成紧密构筑的实性瘤体。这一切提示腺瘤样瘤可能起源于间质内向间皮细胞分化的多能间叶细胞。它们以多中心性生长方式逐步融合而形成瘤体。因此,可将这类肿瘤视为浆膜外间应腺瘤样瘤。
Adenomatoid tumor of the uterus is rare. Its histogenesis has been controversial-.This paper reported 10 cases of adenomatoid tumor of the uterus with clinicopatho-logic and histogenesis study. Two cases were found their earliest stages. One of them,surrounding the main tumor, there were a lot of solitary separate lesions in thestroma of myometrium. These solitary lesions were similar to the main tumor intheir microscopic and histochemical features. In the other case there were manysmall solitary lesions scattered in the stroma of myometrium. They haven't built upa compact tumor yet. These histologic features showed that the histogenesis of theadenomatoid tumor may arise from mesenchymal cells in the stroma of myo-metrium. These solitary lesions proliferated multicentrally and merged gradually into asingle rumor. It may be considered that this is an extraserous membrane mesothelialadenomatoid tumor.
