Ileocolic Intussusception in an Adult Due to Inflammatory Fibroid Polyp: A Case Report

Abstract

The ileocolic region is the most common site of intussusception. It occurs mostly in children but can also occur in adults. Ileal tumors and polyps can cause ileocolic intussusception. Inflammatory fibroid polyp (IFP) is one of the rarest benign tumors of the gastrointestinal tract. The most common sites of IFP are the stomach, ileum, colon, duodenum, and esophagus. Small IFPs can be managed endoscopically but larger IFPs and those with complications such as intussusception require surgical resection. We report a case of ileal IFP presenting with small bowel obstruction due to ileocolic intussusception. The patient was successfully treated by surgical excision. The diagnosis of IFP was made based on a histopathological examination of the resected specimen.

Intussusception in an adult revealing a Vanek's tumor: A case report

“…It stains positive for CD 34 and vimentin and occasionally for smooth muscle actin, calponin, CD 35 and cyclin D1. Unlike mesenchymal tumors, IFTs doesn't stain for CD 117 and S100 [16] . After complete resection, IFTs generally do not recur and the lesion seems to lack malignant potential [1] .…”

Vanek’s tumor: a rare differential diagnosis of colonic submucosal lesions

“…They are usually asymptomatic lesions, but when symptoms occur, they depend on their location and size. The most frequent symptoms when located in the stomach are abdominal pain and gastrointestinal bleeding (1,8) . When they are in the colonic region, they can also generate bloody stools, weight loss, diarrhea, and anemia (9) , as in the present case that generates significant bleeding with hemodynamic instability.…”

“…IFPs are characterized by positive CD34 and vimentin, as well as positive for actin, calponin, CD35 and cyclin D1. Differential diagnoses include gastrointestinal stromal tumor (GIST) which is positive for CD 117, also called c-kit; while IFP does not express it; schwannoma is generally positive for S100 protein; and leyomoma expressing desmin, a muscle cell cytoskeleton protein (8,12) .…”
