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.

Peutz-Jeghers syndrome: its natural course and management.

Two hundred and twenty-two patients with Peutz-Jeghers syndrome were ascertained in Japan between 1961 and 1974 through two nationwide surveys, medical literature, and personal examinations. Genetic analysis was made of this group as well as 102 follow-up cases. The average age at diagnosis was 23 in males and 26 in females, with male to female ratio of 1:1.13. Presenting complaints of 170 patients included obstruction (42.8 per cent of patients), abdominal pain (23.4 per cent), rectal bleeding (13.5 per cent), extrusion of polyp (7.2 percent). Diagnosis of 52 patients was based on melanin pigmentation. Intussusception occurred in 46.9 per cent of the patients, most often in the small intestine. Polyps occurred in the stomach in 108 patients (48.6 per cent), small intestine, 142 patients (64 per cent), colon, 118 patients (53.2 per cent) and rectum, 71 patients (32 per cent). Among the 222 patients, cancer was histologically verified in 28. Fifteen early cancers occurred (3 gastric, 8 small intestine, 4 colon), and 11 advanced cancers (3 gastric, 1 small intestine, 6 colon, and 1 both colon and small intestine). Mortality was lower than in patients with familial polyposis coli but higher than in the general population. Conservative surgical management, planned medical follow-up, and the need for a national registration system are stressed.

The epidemiology of colorectal polyps: prevalence in New Orleans and international comparisons.

Based on a study of the prevalence of intestinal polyps in New Orleans and on international comparisons, the following conclusions are reached. 1) There is a close parallelism in the epidemiology of colon cancer and adenomatous polyps. Both conditions are statistically associated with respect to geography, anatomic localization, socioeconomic class, migration experience and time trends. 2) The strength of the association favors the notion of a direct, positive correlation between multiplicity, size and atypia of polyps, and cancer risk, equivalent to "dose-effect". 3) The epidemiologic findings are coherent with other biologic facts derived from clinical, morphological and experimental studies. 4) Adenomatous polyps are a good epidemiologic indicator of colon cancer risk and their presence should be helpful in advancing from studies of the epidemiology of colon cancer to the epidemiology of precursor lesions.

[Multiple odontomas in Gardner's syndrome].

A case of Gardners syndrome is described. This illness, inherited by autosomal dominance clinically shows multiple soft tumours, osteotomatosis, occasionally also odeontomata and polyposis intestinalis. The almost invariably occuring malignant degeneration of single intestinal polyps has led to the inclusion of Gardner's syndrome into the group of precancerous conditions.
