Pancreatic involvement in von Hippel-Lindau disease: report of two cases and review of the literature.

Background: Von Hippel-Lindau (VHL) disease is an autosomal dominant multicancer syndrome caused by the germline mutation of a tumor suppressor gene. Affected individuals develop benign and malignant tumors of the central nervous system, kidneys, adrenal glands, pancreas, and reproductive system. Although VHL disease is mainly diagnosed after the detection of central nervous system tumors, they may not always be the first presentation.
