MEDICAL EPONYM OF THE WEEK:
Verner–Morrison syndrome: rare pancreatic endocrine tumors that secrete vasointestinal peptides (VIPomas). The tumors are associated with watery diarrhea, hypokalemia, and achlorhydria. The majority (80%) of VIPomas are located in the pancreas and most of these occur in the tail. The prognosis of VIPomas in childhood is more favorable than in adults, because two-thirds of VIPomas are of neurogenic origin and benign. A small percentage of VIPomas (5%) are associated with MEN1.
