Primary carcinoid tumor of the liver.
A primary hepatic tumor with histologic features suggestive of carcinoid tumor is reported, and six previously reported cases reviewed. Tumor cells contained electron dense secretory granules with an average diameter 150-200 nm which demonstrated positive argyrophilic reactions. On immunohistochemistry, chromogranin A was positively stained. No endocrine syndrome was present and an alternative primary source of the tumor was not found, despite an intensive search.
