[VIPoma in retroperitoneum of elderly, cause of chronic diarrhea in uncommon location]. / VIPoma en retroperitoneo de adulto mayor, causa de diarrea crónica en localización infrecuente.

ABSTRACT

Chronic secretory diarrhea is a frequent entity. Causes are multiple, that is why reaching final diagnosis can result in delay with complications that this causes in the general condition of the patient. We present the case of one older adult with chronic diarrhea, mild hypokalemia and metabolic hyperchloremic acidosis secondary to a VIPoma in retroperitoneum which is an unusual location of this type of tumor that was diagnosed by biopsy guided by tomography.
