Abstract

Uterine serous carcinoma is a representative histological subtype of endometrial type II cancer. Uterine serous intraepithelial carcinoma is thought to be a precursor lesion of uterine serous carcinoma. Uterine serous intraepithelial carcinoma is frequently found to involve an endometrial polyp. Preoperative diagnosis of uterine serous intraepithelial carcinoma is difficult due to its localized occurrence in the endometrial cavity. We experienced a case of postmenopausal women with abnormal endometrial cytology. Endometrial biopsy suggested the possibility that she has a malignant uterine tumor, but it did not reached to the confirmative pathological diagnosis. Hysteroscopy revealed that she has an endometrial polyp. Pathological analysis of the resected endometrial polyp confirmed that her disease is uterine serous intraepithelial carcinoma involving endometrial polyp. She underwent hysterectomy, bilateral salpingo-oophorectomy, omentectomy and retroperitoneal lymphadenectomy. No extrauterine lesion was detected. Our case suggested the possibility that transcervical resection under the hysteroscope might be useful to detect serous endometrial intraepithelial carcinoma.

Highlights

  • Uterine serous carcinoma is a representative histological subtype of endometrial type II cancer

  • We report a case of serous intraepithelial carcinoma arising in the endometrial polyp, which was diagnosed by the transcervical resection under hysteroscopy

  • We experienced a case of serous endometrial intraepithelial carcinoma involving endometrial polyp diagnosed with transcervical resection
