Abstract:
Atypical polypoid adenomyoma (APA) most frequently presents as an endometrial polyp in premenopausal women and is believed to follow a benign course. In hysterectomy specimens from postmenopausal Japanease women, the endometrium contained an APA with an area of endometrial adenocarcinoma. A convincing transition zone between the APA and the adenocarcinoma was seen in our cases, suggesting that APA may develop into endometrial adenocarcinoma in postmenopausal women.
