초록
Inflammatory pseudotumor (IPT) is a rare benign tumor of unknown etiology that can occur in almost any organ system. It has neoplasticfeatures such as local recurrence, invasive growth, and vascular invasion, leading to the possibility of malignant sarcomatouschanges. The clinical presentations of colonic IPT may include abdominal pain, anemia, a palpable mass, and intestinal obstruction. Afew cases of colonic IPT have been reported, but colonic IPT with pedunculated morphology is very rare. Furthermore, since it canmimic malignant polyps, understanding the endoscopic findings of colonic IPT is important for proper treatment. Herein, we presenta case of colonic IPT with pseudosarcomatous changes, presenting as a large polyp, mimicking a malignant polyp in the cecum, alongwith a literature review.
Abstract

Afew cases of colonic IPT have been reported, but colonic IPT with pedunculated morphology is very rare. Furthermore, since it canmimic malignant polyps, understanding the endoscopic findings of colonic IPT is important for proper treatment. Herein, we presenta case of colonic IPT with pseudosarcomatous changes, presenting as a large polyp, mimicking a malignant polyp in the cecum, alongwith a literature review.
