Metastatic Serous Carcinoma Initially Presented As An Incarcerated And Strangulated Umbilical Hernia: A Rare Case Report

Introduction: We report a rare case of a metastatic serous ovarian carcinoma presented as an incarcerated and strangulated umbilical hernia.Presentation of case: A 54 year-old female was admitted to the hospital with a painful mass around the umblical region. It was elucidated during clinical history that the mass had been present for 3 to 4 years without pain. An incarcerated and strangulated umbilical hernia including a solid mass and mesenteric fat was detected on physical examination. She underwent an urgent operation for strangulated umbilical hernia. The pathological diagnosis of the hernia material was reported as carcinoma compatible with serous ovarian carcinoma metastasis. Concurrently, total abdominal histerectomy and bilateral salphingo-oopherectomy, pelvic and paraaortic lymph node dissection, omentectomy and sigmoid colon resection were performed. Histopathological evaluation confirmed the serous carcinoma originated from the left ovary.Conclusion: In the literature, some metastatic tumors have been reported to be presented as umbilical metastasis rarely. However, the present case is the first metastatic ovarian cancer that initially presented as an incarcerated and strangulated umbilical hernia in the literature, to the best of our knowledge.
