Diffuse colonic lipomatosis, presenting as perforation peritonitis and mimicking carcinoma colon

Lipomas and lipomatosis of colon are rare in clinical practice. We herein report a case of diffuse colonic lipomatosis, fifth such case in literature which presented as perforation peritonitis, a presentation, never been reported earlier. On laparotomy, the findings suggested malignancy and appropriate surgery was done. Diffuse Colonic Lipomatosis, a rare and benign condition mimicks malignancy and should be kept as a differential diagnosis is unusual cases of colonic perforations.
