Intestinal polyposis associated with oxyurid parasites in a chimpanzee (Pan troglodytes).

A 40-year-old male chimpanzee had multiple intestinal polyps associated with immature male oxyurid parasites. The gross and histologic characteristics of these lesions were identical to those produced by Nochtia nochti in the stomach and esophagus of Old World primates. It was theorized that the lesions resulted from hypersensitivity to oxyurid infection in an aberrant host.

Inflammatory pseudotumors (inflammatory fibrous polyps) of the small intestine: A clinicopathologic study.

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.
