OVARIAN FIBROMA – RARE CASE REPORT

Introduction. Primary ovarian leiomyoma is a rare benign solid tumor of the ovary seen in women between 20 and 65 years old. They belong to stromal cellular tumor which present 4% of all ovarian tumors. In 90% they are unilateral and, in more cases, appear in postmenopausal period. Very rare in young years. Abdominal pain could be only symptom. Only pathological examination can establish the diagnosis. Case presentation: We describe a case of bilateral, ovarian leiomyoma. The ultrasound and magnetic resonance imaging (MRI) revealed an adnexal mass. adnexal preservation was performed, and histological examination revealed a leiomyoma of the ovary. The diagnosis was confirmed immunohistochemically. Discussion. The tumor may be asymptomatic or may manifest with lower abdominal pain associated to algodismenorhea, like in our case. The definitive diagnosis of these lesions is difficult prior to surgical removal. Because there is no pathognomonic symptoms or characteristic imaging findings. The correct diagnosis of an ovarian leiomyoma is confirmed immunohistochemically. Conclusion. This rare tumor of the ovary is difficult to diagnose before surgery. Clinically and biochemically, there may be similarities with other formations, such as: benign tuboovarian masses, malignant ovarian formation, uterine myoma. The final diagnosis is made morphologically after surgery.
