A giant lipoma of the parietal peritoneum: Laparoscopic excision with the parietal peritoneum preserving procedure - a case report with literature review.

Background: Lipomas are very common benign tumors of mature fatty tissue that can occur in any part of the body. However, lipomas of the parietal peritoneum are extremely rare.

Case Presentation: A 36-year-old man presented with urinary frequency for 6 months. On computerized tomography of the abdomen and pelvis, a well-defined fatty mass measuring 20 × 11 × 6.5 cm in size, was found in the lower abdominal cavity. We performed a laparoscopic parietal-peritoneum-preserving excision of the mass. The patient was discharged without complications on post-operative day 6.

Conclusions: To our knowledge, a laparoscopic excision with preservation of the parietal peritoneum for a giant parietal peritoneal lipoma has never been reported. Herein, we report a case of a giant lipoma of the parietal peritoneum successfully managed by laparoscopy.
