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

摘要

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. 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. 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.
