Primary Leiomyoma of ovary – A rare case report presenting with clinical diagnosis of subserosal uterine fibroid

Primary leiomyoma of ovary are rare benign ovarian tumors. We present a rare case report of ovarian leiomyoma who was planned for laparotomy with a clinical diagnosis of subserosal uterine fibroid. Twenty three years old unmarried girl presented with heaviness and mass in lower abdomen, gravid uterus size of 20 weeks. Abdominal Ultrasonography raised suspicion of subserous fibroid. MRI pelvis was suggestive  of ovarian neoplasm versus broad ligament fibroid. On laparotomy and removal of mass, histopathology and immunohistochemistry confirmed leiomyoma of ovary. Presently she is on follow up without any complaints. Ovarian leiomyoma is clinically often misdiagnosed and should be kept in differential diagnosis in lower abdominal masses.
