Abstract

Highlights: We present a very rare case of advanced ovarian cancer. This is the first report of metastasis to a hydrocele in the canal of Nuck. Ovarian cancer can metastasize to a hydrocoele in the canal of Nuck in adult women. Abstract: Introduction: Ovarian cancer has few subjective symptoms, so approximately 40%–50% of cases have already reached stage III or IV by the time of diagnosis. These are advanced stages of the disease and have poor prognosis. Among these cases, less than 3 % are reported to exhibit inguinal lymph node metastasis. This report documents a rare case of advanced ovarian cancer that we detected due to an inguinal metastasis in the canal of Nuck. The work has been reported in line with the SCARE criteria. Presentation of Case: The patient was a 43-year-old, married, premenopausal woman (G2P1). She was examined by her local practitioner for a chief complaint of a mass in the right inguinal region and was found to have a right inguinal mass. Magnetic resonance imaging (MRI) scans revealed a left ovarian tumor, and she was referred to our department. Rapid intraoperative diagnosis showed a highly atypical serous carcinoma present in both the left ovary and the right inguinal region mass, where the tumor had extended into the canal of Nuck. Discussion: In this case, the right inguinal mass was ovarian cancer that had metastasized to a cyst in the canal of Nuck via the round ligament of the uterus. Though, many adult women with these types of inguinal hydrocoeles sometimes undergo fine-needle aspiration. Conclusion: This finding may highlight the need for a careful search for metastasis to the inguinal region in cases of ovarian cancer.
