A CHALLENGING CASE OF VOLUMINOUS OVARIAN FIBROTHECOMA MIMICKING MALIGNANCY: DEMONS-MEIGS SYNDROME

Demons-Meigs syndrome is a rare clinical entity characterized by a benign ovarian tumor associated with ascites and pleural effusion, which resolve after tumor removal. We report the case of a 68-year-old postmenopausal woman diagnosed with a large ovarian fibrothecoma, initially suspected of malignancy due to massive ascites and an elevated CA-125 level. The final histopathological diagnosis confirmed a benign fibrothecoma. Surgical treatment led to a complete resolution of symptoms, supporting the diagnosis of Demons-Meigs syndrome. This case highlights the challenges in distinguishing fibrothecoma from malignant ovarian tumors and underscores the importance of histopathological confirmation.
