“…Several studies have shown that IFPs are immunohistochemically are positive for vimentin, CD34, fascin, calponin, Cyclin-D1, PDGFRA and SMA, and negative for CD117, unlike GIST [ 256 , 259 , 260 ]. Local removal is usually curative [ 263 ].…”

“…1 snare polypectomy has been accepted as the treatment modality of choice in most patients with inflammatory polyps. 2,3 surgical interventions might be required when snare polypectomy was not eligible. 1 Here we reported on two IBD patients whose inflammatory polyps were fibrotic and initially resistant to hot snare polypectomy, but were successfully resected with the assistance of endoscopic needle-knife.…”

Background Inflammatory polyps are common sequelae in patients with inflammatory bowel diseases (IBD). Those polyps can usually be removed with snare polypectomy. There were limited data evaluating the management of hot snare-resistant inflammatory polyps. Methods We reported on two cases with hot snare-resistant inflammatory polyps, one was a Crohn's disease (CD) patient with the polyp at the ileo-colonic anastomosis (ICA) and the other one was an ulcerative colitis (UC) patient with polyp at the pouch inlet. Results Sedated endoscopy was performed, which showed a large 2.5 cm pedunculated polyp at the ICA in the first patient and a large 5 cm pedunculated polyp at the pouch inlet in the second patient. Hot snare polypectomy was initially attempted, but failed in both patients. Then endoscopic needle knife polypectomy was performed, which helped complete polypectomy. Both procedures took approximately 25 minutes each. The patients tolerated the procedure well and continued to do well after the procedure. The final pathological diagnoses for both patients were inflammatory polyps with extensive fibrosis. Conclusions Endoscopic needle knife-assisted polypectomy appeared to be an effective technique for the management of hot snare-resistant inflammatory polyps.

“…Most IFPs occur in the gastric antrum and small intestine [1–4]. IFPs are extremely rare in the colon and rectum [1–4]. Histologically, an IFP is characterized by a mixture of numerous small vessels, fibroblast‐like spindle cells, and edematous connective tissue associated with marked inflammatory infiltration by eosinophils and plasma cells [5].…”

“…Clinical symptoms may depend on the macroscopic appearance of the lesion and its location in the gastrointestinal tract. Although no specific symptom can be associated with colorectal IFP, anal bleeding and abdominal pain are the most common symptoms [2,3]. Surgical intervention is usually required for most symptomatic IFPs because of their large size and submucosal involvement [11].…”

Inflammatory fibroid polyp of rectum mimicking rectal cancer

Inflammatory fibroid polyps (IFPs) are rare benign tumors of the rectum. Mutation and activating platelet-derived growth factor receptor alpha (PDGFRA) contribute to tumor development. We present a case of IFPs in the middle rectum that mimic rectal cancer. A 65-year-old woman presented with the symptom of fresh blood in the stool and body weight loss of 6 kg in the preceding 3 weeks. A rectal polypoid tumor was noted upon digital examination. Sigmoidoscopy showed a middle rectal tumor measuring 3 × 2.7 cm with obstruction. Computed tomography (CT) scans of the abdomen showed a rectal tumor that had invaded the sacral bone and was associated with four enlarged lymph nodes greater than 1 cm. The radiological report suggested a diagnosis of rectal cancer with lymph node metastases. To remove the obstruction, the patient was initially treated with excision of the tumor and loop sigmoidal colostomy to the abdomen wall. Total mesorectal resection of rectal and sacral tumor followed 10 days later. Histopathological examination of the rectal and sacral tumor showed proliferation of vessels, fibroblast-like spindle cells, and mixed inflammatory cells, including the plasma cells and eosinophils. The spindle cells were diffusely positive to PDGFRA and were focal positive to CD34 and smooth muscle actin. Based on histopathological and immunohistochemical findings, the diagnosis of IFP is indicated. This was the first reported case of IFPs of the rectum presenting with lymph node enlargement and attachment to the sacrum mimicking rectal cancer.
