RESUMO
VIPoma of the Pancreas Abstract. A 50-year old man was admitted for evaluation of progressive, chronic diarrhea with loss of weight and recurrent hypokalemia. Eventually, a neuroendocrine tumor of the pancreas secreting VIP (VIPoma) could be diagnosed. The patient was cured by a pancreaticoduodenectomy (Whipple procedure). With this case, we want to highlight the importance of a structured work-up in chronic diarrhea including thorough history and clinical assessment, laboratory tests and imaging studies.

Hemangiosarcomas are rare tumors of endothelial cell origin. To date, only 20 cases of hemangiosarcoma have been described after renal transplantation, occurring mostly in the skin or in a dialysis fistula. We report a primary metastasizing hemangiosarcoma arising from a renal allograft. The patient was treated with transplant nephrectomy, discontinuation of immunosuppression, and immunostimulation with pegylated interferon-α-2a and has now been in complete remission for 3 years.
