Introduction: Ovarian fibroma is a benign stromal tumor composed of spindle fibroblasts like cells that produce collagen. It is seen in perimenopausal and postmenopausal women and is seldom seen in women with the age of less than 30 years. Case description: A young lady presented with irregular menses and secondary amenorrhoea of 8 months with gradual distension of abdomen. Raised Ca-125 levels with CECT impression raised the suspicion of malignant right ovarian tumor. Staging laparotomy was done followed by right salpingo-ovariotomy. Histopathology with immunohistochemistry confirmed the diagnosis of ovarian fibroma. Conclusion: There are no specific markers for an accurate pre-operative diagnosis of an ovarian fibroma. Improved understanding of this entity is essential to prevent misdiagnosis and missing the diagnosis.
