Primary neuroendocrine carcinoma of the liver: an autopsy case
Abstract
An autopsy case of primary hepatic neuroendocrine carcinoma is described. A 72-year-old man had a large tumor mass measuring 22 cm in its greatest diameter and localized to the right, left and caudal lobes of the non-cirrhotic liver. Microscopically, the tumor was composed of middle-sized pleomorphic cells organized in ribbons or trabeculae, with scanty intersecting fibrous septae. Immunohistochemically, the tumor cells were positive for multikeratin C11, chromogranin A and synaptophysin. The patient also had metastases in the bone marrow. No alternative primary source of endocrine tumor was detected. The patient died 4 days after presentation.
