“…Invagination is rarely the mode of discovery of intestinal lipoma. The latter is often found on the caecum or ascending colon [5] [6] and more rarely on the left colon. Theoretically speaking, lipomas can affect any segment of the digestive tract from the hypopharynx to the rectum.…”

Intussusception in adults is rare and accounts for 1% to 5% of cases of acute bowel obstruction. Moreso, colic intussusception remains exceptional in adults and is usually secondary to an endoluminal lesion. Abdominal intestinal lipomas are rarely responsible for colonic invagination. They are often located on the caecum or the ascending colon and rarely on the left colon. We report the case of colo-colic invagination on a descending colon lipoma in a 50-year-old woman.

“…Most of the reported cases of colonic lipoma were located submucosal (90%) or subserosal (10%) 2,15 , 16 . As far as we know, there has been only three cases of intramuscular colonic lipoma, although not all of the reports presented convincing pictures 3,17 , 18 . It is easy to understand the histogenesis of submucosal or subserosal lipoma because the submucosal or subserosal layer physiologically contains fat tissue.…”

A unique case of repeatedly intussuscepted colonic lipoma mimicking an epithelial tumor in a 50-year-old man is reported. The tumor was located in the ascending colon and was approximately 5 cm in diameter. Colonoscopic and barium-enema examinations suggested a huge epithelial tumor because of its nodule-aggregating appearance. In contrast, computed tomography examination showed a fatty element in the core of the lesion. The biopsy specimens suggested a primary angiomatous lesion because of its pronounced vascular proliferation. Because the presumed diagnoses based on the examinations were different, the preoperative diagnosis was not confirmed. The tumor was composed of intramural lipoma with a multiple polypoid mucosa overlay. This lesion was unique in that the lipoma appeared to be within the muscularis propria and the multiple polypoid appearance of its covering mucosa. The mucosal changes including florid vascular proliferation, fibromuscular obliteration and epithelial regeneration suggested a reparative process, with ischemic damage due to the effects of intussusception being the most likely event. It should be kept in mind that even a simple lipoma can have a unique appearance reminiscent of epithelial tumor when it repeatedly experiences intussusception.

“…They can be detected anywhere along the intestinal tract from the hypopharynx to the rectum. 12 Intestinal lipomas have been identified as simple Iipoma, lipomatous polyp, and focal lipomatous hyperplasia. Most are located underneath the muscularis mucosae and over the muscularis propria.…”
