Benign multicystic mesothelioma of the peritoneum (BMMP) is an uncommon benign tumor that arises from the peritoneum in women of reproductive age. Associated risk factors include endometriosis, pelvic inflammatory disease, and previous abdominal surgery. However, etiopathogenesis is still unknown. The preoperative diagnosis of BMMP is challenging and is confirmed by pathology.
We report a case of a 22-year-old woman with no medical history who presented with abdominal pain at her one-month checkup after a vaginal delivery a month prior. Contrast-enhanced magnetic resonance imaging showed a multifocal tumor on the ventral side of the uterus. Diagnostic laparoscopy revealed multiple cysts adherent to the peritoneum and omentum. BMMP was diagnosed based on the pathology report, and follow-up did not reveal any recurrence for nine months.
The prognosis for BMMP is excellent, despite the high recurrence rate of 50%. Although there is no standard algorithm for the treatment, surgery is considered the primary treatment because of its high recurrence rate after the resection. Long-term follow-up is necessary, and diagnostic laparoscopy is useful given the high recurrence rate.
