Abstract:

We report the case of a 49-year-old woman with isolated, unilateral, ovarian metastasis of endocervical adenocarcinoma in situ four years after undergoing total hysterectomy. Extensive workup (including colonoscopy and upper endoscopy) excluded other sites of active disease. Histopathology review confirmed the absence of an invasive component of endocervical adenocarcinoma and both tumor samples had the same histological characteristics and were P16positive tumors by immunohistochemistry analysis, supporting the interpretation of the ovarian neoplasms as a late recurrent of endocervical adenocarcinomas, simulating primary ovarian surface epithelial neoplasms. The patient underwent bilateral oophorectomy with complete tumor resection, followed by six cycles of chemotherapy. The patient remains alive with no evidence of disease after seven years of follow-up. The lack of recognizable stromal invasion, absence of lymph node involvement, and distal organ metastasis make transtubal spread the most likely route of dissemination in this presented case, and it might not result in an adverse outcome.
