title: Inflammatory pseudotumors (inflammatory fibrous polyps) of the small intestine: A clinicopathologic study.
abstract: The clinical and pathologic features of 25 inflammatory pseudotumors of the small intestine are reported. These rare lesions, which clinically may simulate neoplasms, consist of localized, frequently polypoid masses composed of inflamed fibrous and granulation tissue. Inflammatory pseudotumors may produce intussusception and small-bowel obstruction. Some are found at laparotomy performed for other reasons. The diagnosis of inflammatory pseudotumor usually can not be made until the lesion is examined histogically. Their etiology remains unknown, but their relationship to intestinal ulceration is discussed. Problems in differential histologic diagnosis are considered.
