Carcinoma of Meckel's diverticulum; report of case with summary review of the literature.

DESPITE the rather recent voluminous literature concerning Meckel's diverticulum and despite the great variety of pathological conditions encountered in this structure, carcinoma originating in Meckel's diverticulum remains a surgical and a pathological curiosity. In 1939 Skinner and Walters, 1 in a comprehensive review of the subject, found six authenticated cases of carcinoma arising in a Meckel's diverticulum, and since that date three additional case reports have appeared. We wish now to add one more case report, which will be the 10th recorded in the literature available to us. Meckel's diverticulum, said to be present in 2% of all adults, results from incomplete closure of the yolk stalk (omphalomesenteric duct) during the fourth or fifth week of fetal life. The diverticulum is, as a rule, located on the antimesenteric border of the ileum at a distance of 25 to 100 cm. proximal to the ileocecal valve, but, according to Nygaard and
