Mixed endocervical adenocarcinoma and high-grade neuroendocrine carcinoma of the cervix: A case report

Abstract

Adenocarcinoma admixed with neuroendocrine carcinoma of the uterine cervix is a rare malignancy with a poor prognosis. In the literature, there are few reported cases. Herein, we report a case of a 56-year-old Turkish woman with cervical adenocarcinoma admixed with small cell neuroendocrine carcinoma. Histological examination of endocervical curettage specimens revealed a tumor composed of almost equal areas of small cell neuroendocrine carcinoma and adenocarcinoma. Neuroendocrine differentiation was confirmed by immunohistochemistry for chromogranin-A, synaptophysin, and CD 56. After the adenocarcinoma and small cell neuroendocrine carcinoma association was detected in the curettage material, both cervicovaginal smear and then total abdominal hysterectomy and bilateral salpingo-oophorectomy resection material of the patient were submitted to our pathology department. Histological features of both curettage and resection material were determined by immunohistochemical studies.
