Diffuse Colonic Lipomatosis, Presenting as Perforation Peritonitis and Mimicking Carcinoma Colon

Abstract

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.

Rare diagnosis of intestinal lipomatosis complicated by intussusception in an adult: A case report

“…Lipomas can be found diffusely throughout the intestines with most being asymptomatic. Invasive management is not advised unless complications arise such as intussusceptions, obstruction, bleeding, or perforation leading to peritonitis [9] , [10] . Intussusception was amongst the most rare of complications [2] .…”

Caecal lipomatosis as a cause of colic in a 9‐year‐old gelding

“…Benign lipomatous lesions of the intestine may present as either encapsulated single or multiple lipomas, or alternatively as diffuse and discrete nonencapsulated lobules of adipose tissue (Sandhu et al . 2011).…”

“…2012). Although considered benign histologically, lipomatosis often results in massive tissue infiltration and expansion, with this type of growth mimicking malignancy (Sandhu et al . 2011).…”

“…Benign lipomatous lesions of the intestine may present as either encapsulated single or multiple lipomas, or alternatively as diffuse and discrete nonencapsulated lobules of adipose tissue (Sandhu et al 2011). Single or multiple abdominal lipomata are commonly seen in horses, both as incidental findings at laparotomy or necropsy and as a cause of colic.…”

“…In contrast, infiltrative intestinal lipomatosis is an uncommon neoplasm, with limited published reports in the human literature and only 3 previously reported cases in horses (Henry and Yamini 1995;Riley et al 2007;Linnenkohl et al 2012). Although considered benign histologically, lipomatosis often results in massive tissue infiltration and expansion, with this type of growth mimicking malignancy (Sandhu et al 2011). Histologically, adipose proliferation may be confined to the submucosa or may extend to the mesenteric and serosal layers, while the muscularis mucosa is usually unaffected (Shenoy et al 2003).…”
