Abstract

A case of primary neuroendocrine carcinoma in an unusual location, the liver, is reported. The neoplasm was composed of small, uniform cells that had distinct borders and grew in strands, ribbons and nests; its appearance resembled that of a carcinoid. Electron microscopy and special staining of the neoplastic cells confirmed the neuroendocrine nature of the tumor, and the cells showed immunoreactivity for gastrin and pancreatic polypeptide by the PAP. The recent literature is reviewed, and the possible histogenesis of hepatic neuroendocrine carcinoma is discussed.
