The condition of aberrant or accessory pancreas was first described by Klob in 1859. In 1860 Montgomery cited a case which was recorded by Bristowe in his book of necropsies in 1851, in which a pancreatic nodule ¾ in. (1.9 cm.) in diameter and ⅓ in. (0.83 cm.) thick was found in the wall of the ileum. The nodule was in the middle of the ileum and was lobulated in appearance. As early as 1727 Jean Schultz reported a case which, although it is not authentic, as there is no proof that the nodule found was pancreatic, is interesting from a historical standpoint. He wrote that he found at autopsy in a new-born child "a wart similar to a gland" in the apex of a cone-shaped diverticulum of the ileum. The diverticulum was 4 cm. long and was situated 10 cm. from the ileocecal valve.
