Lipomas are common benign
tumors of mature
adipose tissue, enclosed by thin fibrous
capsules. They can occur on any part of the body; however, peritoneal
lipoma is extremely rare. We encountered a case of a 75-year-old man presenting with intermittent
abdominal pain,
who had undergone right
hemicolectomy due to
colon cancer. Abdominal computerized
tomography showed a well-defined heterogenous fatty mass measuring 4.5x3.5 cm in size, suggesting
fat necrosis located in the
abdominal wall.
Laparotomy showed a very large soft mass of
peritoneum. Pathologically, the
tumor was diagnosed as
lipoma containing
fat necrosis located in
parietal peritoneum not fixed to any organs, but with small bowel adhesion. Due to its rare etiologic origin and obscure cause of development, we
report on a case of
lipoma of
parietal peritoneum causing
abdominal pain.
