Duodenal paraganglioma - A case report

Abstract

Gangliocytic paraganglioma (GP) is a rare tumor of the duodenum. Worldwide, less than 300 cases have been documented. According to cases previously reported, the tumor is frequently seen in the second part of the duodenum. In this article, we discuss the case of a young adult who had a metastatic lymph node discovered to be due to a GP in the fourth portion of the duodenum. These duodenal lesions are commonly confused with neuroendocrine neoplasms, which are of epithelial origin, and are distinguished from them using immunohistochemistry.
