The occurrence of aberrant pancreatic tissue, discovered either at operation or at autopsy, has been reported from time to time since the first case was described by Klob 1 in 1859. From that date until 1904, when Warthin 2 made the first comprehensive study of the literature, reports of isolated cases were published. Warthin collected forty-seven cases, to which he added two.
