Giant Preperitoneal Lipoma: An Unusual Case Report with Literature Review

Abstract

Lipomas are the most common and benign soft tissue neoplasms that can occur throughout the body. Intraabdominal lipomas, especially those located in the preperitoneal region, are very rarely detected. These lipomas can be manifested with discomfort or bloating, pain or palpable mass in the abdomen, and many of them can be detected incidentally during a radiological examination or surgery for a different reason. Surgical resection is necessary only in cases of pain, cosmetic reasons, rapid growth or uncertainty in the diagnosis. Lipomas such as mesentery, omentum and retroperitoneum are very rare in the abdominal cavity. The number of reported cases of parietal peritoneum is 7 so far. Lipomas can reach large volumes very rarely. In the literature, only one excessively large lipoma case was reported. In this case report, the diagnosis and treatment of a very rare giant preperitoneal lipoma detected in a female patient is presented with literature review.
