We studied a case of intramural müllerian adenosarcoma of the uterus in a 51-year-old woman. The tumor measured 4 cm in diameter, was located in the lateral wall of the uterine body, and was accompanied by adenomyosis. The tumor was composed of glands with no epithelial cell atypia and a sarcomatous component evidenced by cell pleomorphism and a high mitotic count. The ratios of mitotic cells to glandular cells in the tumor, in the overlying endometrium in proliferative phase, and in the adenomyomatous tissue, were 5:10,000, 20:10,000, and less than 1:10,000, respectively. These observations seem to indicate that the glandular component of the tumor is a benign, neoplastic part, and the present tumor developed in a preexisting endometriotic focus.
我们研究了一例51岁女性子宫壁内苗勒管腺肉瘤的病例。肿瘤直径4厘米，位于子宫体侧壁，伴有子宫腺肌病。肿瘤由无上皮细胞异型性的腺体和具有细胞多形性及高有丝分裂计数的肉瘤成分组成。肿瘤、增殖期的上层子宫内膜以及腺肌瘤组织中有丝分裂细胞与腺细胞的比例分别为5:10,000、20:10,000和小于1:10,000。这些观察结果似乎表明，肿瘤的腺体成分是良性的肿瘤部分，且当前肿瘤是在先前存在的子宫内膜异位灶中发生的。
