Neuroendocrine tumor in the liver of a patient with isolated polycystic liver disease: A case report and review of the literature.

Neuroendocrine tumors (NETs) frequently metastasize to the liver, but it is rare to find them there as primary tumors. Isolated polycystic liver disease (PCLD) is a rare autosomal dominant disease. There is no known association between polycystic liver disease and neuroendocrine or other tumors.
