Primary hepatic carcinoid tumors are extremely rare neoplasms derived from hormone-producing neuroendocrine cells. It is difficult to make their diagnosis before biopsy, surgical resection or necropsy. A recent publication described only 94 cases of these tumors. There is no sex predilection and apparently it has no association with cirrhosis or preexisting hepatic disease. The most effective treatment is hepatectomy, and resection is determined by size and location of the lesions.
