An Inflammatory Fibroid Polyp of the Descending Colon Associated with Intussusception—A Case Report—

Abstract

A 70-year-old man presented with abdominal pain and bloody stools. An abdominal computed tomography showed that the descending colon was invaginated. Intussusception resolved spontaneously, and a submucosal tumor-like lesion was found upon colonoscopic examination. We performed laparoscopic resection of the descending colon to rule out the possibility of malignancy and to prevent recurrence of intussusception. Grossly, the resected specimen revealed the presence of a 2.0×1.3×1.0 cm submucosal tumor-like lesion with a peduncle on the descending colon. Histopathological findings revealed proliferating fibrous connective tissue and small blood vessels with inflammatory cell infiltration. Neither recognizable malignant findings nor tumorous lesions were found. These findings led to the diagnosis of intussusception caused by an inflammatory fibroid polyp (IFP). He was discharged on the 7^th postoperative day.

IFP associated with intussusception of the colon is a rare condition. Here, we report such a case resected laparoscopically, along with a review of the literature.
