Ovarian fibrothecomas are ovarian stromal tumors that can appear in a variety of clinical circumstances. Aim: In postmenopausal bleeding women, the study's goal is to determine the prevalence, diagnosis, therapeutic needs, and histological characteristics of ovarian fibromas and fibrothecomas. Case description: We present a case of ovarian fibrothecoma with postmenopausal bleeding and abdominal distension in a 64-year-old female with chronic renal disease, measuring 84.96 pg/mL serum testosterone and 18.5 ng/dL serum inhibin-B. A multiseptated cystic lesion measuring 3.6 × 2.4 cm with thin internal septae emerging from the right ovary is shown on MRI pelvis. Total abdominal hysterectomy was performed, as well as bilateral salpingo-oopherectomy. Conclusion: Ovarian fibrothecoma is a rather uncommon condition. The preferred treatment for postmenopausal women is surgical excision, which has an excellent prognosis. In our case, ovarian fibrothecoma with thickened proliferative endometrium, raised CA-125 level, and increased inhibin-B and serum testosterone levels mislead us to the diagnosis as malignancy. This case report represents the possibility of occurrence of benign ovarian tumors with clinical pictures of postmenopausal bleeding and to be wide enough to rule out benign causes.
