Rectal neuroendocrine tumor presenting as a polyp with hepatic metastases

A 59-year-old woman with no medical history presented because of pain in the right hypochondrium and loss of weight. Abdominal examination showed hepatomegaly, and laboratory test results showed increased liver enzymes. Abdominal examination and CT showed multiple hepatic metastatic lesions with enhancement after injection, the biggest one involving the left lobe of the liver (A). Her levels of angiotensin-converting enzyme, carbohydrate antigen 19-9, and α-fetoprotein were normal. The result of upper endoscopy was normal, whereas colonoscopy revealed an ulcerated sessile rectal polyp measuring 15 mm (B).
