title: Hysteroscopic diagnosis of malignant mixed müllerian tumor of the corpus uteri.
abstract: Hysteroscopic findings of two cases with homologous type of malignant mixed müllerian tumor of the corpus uteri are described. On hysteroscopic examination, not only were nodular or polypoid lesions with fairly smooth surfaces found but also lesions with rough uneven surfaces and dilated vessels resembling the figures of endometrial carcinoma were observed. The blood vessels of lesions with fairly smooth surfaces were not dilated. Under hysteroscopy, each lesion with a smooth surface seemed to be more closely related to a benign lesion, such as an endometrial polyp or submucous myoma. The lesions with smooth surfaces corresponded to the histologically sarcoma-dominant areas and the lesions with uneven surfaces and dilated vessels were equivalent to the sites where adenocarcinoma was noted. Thus, hysteroscopic findings of this tumor well reflected the histology near the surface of the endometrium.
