Papillary serous carcinoma arising from adenomyosis presenting as intramural leiomyoma.

Abstract

Adenocarcinoma arising from adenomyosis uteri is rare. Herein, we reported a patient with papillary serous carcinoma arising from adenomyosis. The patient was a 61-year-old woman who received tamoxifen for treatment of her breast cancer over the past five years. In hysterectomy specimen taken for investigating her uncontrolled bleeding with suspicion of uterine myoma, multiple adenomyotic foci were found in the uterine wall. In one of these foci, papillary serous carcinoma was found. No evidence of tumor was seen in endometrial surface, peritoneum, and both adnexa.
