Background: Inflammatory fibroid tumor (IFT) is uncommon tumor in large bowl. In this patient it was the unusual cause for large bowel intussusception. More over the coexistence of mucinous adenocarcinoma arising from adenomatous polyp is a rarity previously unreported in the world literature. Case presentation: Here, we present the case of a 65 year old female who complained of lower abdominal pain with rectal bleeding occasionally. Imaging studied confirmed the diagnosis of intussusception of ileocecal type. After resection of intestines, two sessile polyps in caecum were detected. Histology of the polyp’s revealed one showing classical features of IFP and the other a malignant growth arising from tubular adenoma with deep invasion upto serosal coat. Unusually IFP lacks CD 34 stromal cells. Conclusions: Intussusception of ileocecal type due to sessile polyps in caecum is a rare surgical event. The heterogenous nature of these polyps being the cause for this unusual case is previously unreported.
