Serous endometrial intraepithelial carcinoma coexistence with atypical polypoid adenomyoma in a young woman: a rare case

Background. Atypical polypoid adenomyoma (APA) is a rare lesion with less than 500 cases reported worldwide (in the literature). It is an unusual tumor of the uterus, first described by Mazur in 1981 that typically develops in young women, which are also associated with infertility. The disease is considered benign, but there is a significant risk of developing an endometrial carcinoma or a risk of recurrence. The most common histological type of associated adenocarcinoma is endometrioid endometrial carcinoma.
Case presentation. In this study we present a case of APA concomitant with a serous endometrial intraepithelial carcinoma (SEIC) in a young woman, an occasion that has not been reported yet.
Conclusions. When a patient is diagnosed as having APA, always an accompanying EC must be carefully searched.
