    Abstract:
    A primary hepatic carcinoid tumor arising in a 77-year-old woman is reported. The patient was admitted with a huge tumor in the right lobe of the liver and treated by an extended right lobectomy of the liver. Light microscopic findings showed that the tumor cells had small oval-shaped nuclei and eosinophilic cytoplasm with small granules forming trabecular, glandular, and rosette patterns. Immunohistochemically, tumor cells were stained positive with neuron-specific enolase and synaptophysin and were stained slightly positive with chromogranin and carcinoembryonic antigen. Careful examination before and after the operation revealed no other origin of the tumor. Based on the findings, the liver tumor was diagnosed as a primary carcinoid. The clinical features and diagnosis of this rare tumor are discussed in this report.
