De novo growth of a large preperitoneal lipoleiomyoma of the abdominal wall

Abstract Background Extrauterine lipoleiomyomas are an uncommon finding, especially in the preperitoneum. These benign tumors have been attributed to seeding after surgical fibroid resection, exogenous hormonal therapy, or major disturbances in glucose metabolism. Case We are reporting the case of a postmenopausal woman without any history of gynecological surgery, hormonal therapy, or significant metabolic abnormality who developed a large, symptomatic, preperitoneal lipoleiomyoma requiring resection. The patient had an uneventful recovery with full resolution of her symptoms. Conclusion Our case relates the first description to our knowledge of the de novo growth of a large lipoleiomyoma in an incisional umbilical scar independent of gynecological pathology or hormonal influence.
