Concomitant mucin-producing tumors of ovary and adenocarcinoma of cervix: a case report

Ovarian mucinous borderline tumors are divided into two morphologic groups: endocervical-like and intestinal type. Most endocervical adenocarcinomas exhibit mucinous and/or endometrioid differentiation، they infrequently metastasize to the ovaries but may simulate primary ovarian tumors (both atypical proliferative or borderline and carcinoma). In patients with mucinous adenocarcinoma in the abdominal cavity، caution should be exercised in interpreting the possible primary site of the tumor on the basis of the immunohistochemical profiles. The presence of human papillomavirus (HPV) DNA is assessed to determine whether the ovarian neoplasms were metastases or primary independent neoplasm. Approximately 90% of endocervical adenocarcinomas are related to high-risk human papillomavirus (hr-HPV) with the remainder being unrelated to HPV. Both types metastasize to the ovaries very infrequently. Ovarian endocervical-type (mullerian) mucinous tumors and tumors composed of a mixture of endocervical-type mucinous، serous endometrioid، squamous، and indifferent cells with abundant eosinophilic cytoplasm reported to date have been primarily limited to borderline and micro invasive types. We report a-36-yr old woman with adenocarcinomas of uterine cervix who also had ovarian mucinous borderline tumor. The patient presented with abnormal uterine bleeding and lower abdominal pain. She had a history of uterine cervix polyps. Pelvic ultrasound showed a right adnexal mass and a large cervical size. Histological diagnosis in uterine cervix biopsy revealed adenocarcinoma of cervix. Radical hysterectomy type III with bilateral salpingo-oophorectomy was performed. Histological finding in adnexal mass revealed borderline mucinous tissue of ovarian tumor. Testing for HPV DNA in the tumoral tissue was negative. This confirms that the ovarian tumor is not metastatic from endocervical adenocarcinoma. We conclude that in a patient with tumors that involve two organs، complete diagnostic investigation should be done to distinguish the primary origin. The factors that affect cell proliferation، can probably have synchronous effects on the two similar cells.
