Villous adenomas are a type of adenoma with a high potential for malignant transformation, frequent in the colon (rectum, sigmoid and right colon). Generally asymptomatic, they can be hypersecretory causing diarrhea and significant fluid and electrolyte depletion, a condition called McKittrick-Wheelock syndrome. Those of larger size and distal are at greater risk of developing this syndrome. We present the case of a 69-year-old male, with diarrhea for a year, hospitalized for dehydration and electrolyte disturbance. Imaging and complementary studies with a large tumor in the rectum; histopathological result invasive adenocarcinoma with precursor lesion villous adenoma integrating the clinical entity of McKittrick-Wheelock syndrome.
