Abstract
A 22 year-old male with juvenile polyposis coli was reported. On roentogenographic and endoscopic examination nine polyps were recognized in the colon and rectum. Six of the nine polyps were pedunculated and were removed by endoscopic polypectomy. Biopsy specimens were taken from the other three sessile polyps. Histopathologically, those polyps but one with adenomatous structure showed cystic dilatation of the tubules and abundant stroma. From these findings this case was compatible with juvenile polyposis coli, on which McColl et al, reported for the first time in 1964. This is a very rare disorder. The number of reported cases in Japan is only nine, and that from foreign countries is about 70. This case had several gastric polyps in the antrum. Their histological features were similar to those of colonic juvenile polyps. Approximately ten cases with concomitant gastric polyps have been reported up date. Those histological diagnosis was hyperplastic polyp or juvenile polyp. Therefore, juvenile polyposis coli may be a disease entity involved in total gastrointestinal polyposis. This case had moderate splenomegaly, however, the etiology was unknown. He has no complaint now, a year after polypectomy.
