A pyogenic liver abscess is a final common pathway of many pathologic processes, mainly suppurative cholangitis or suppurative pyephlebitis, arising from abdominal or pelvic infection. There are many other etiologies, and some abscesses are idiopathic-namely, cryptogenic abscess. We present a case of a man with a pyogenic liver abscess. This was the clue for the diagnosis of a large but clinically silent villous adenoma of the colon. Colonic tumors, manifested clinically as an hepatic abscess, in the absence of liver metastases, are very uncommon. This is the first description of a villous adenomatous tumor with such a presentation.
