Duodenal gangliocytic paraganglioma with lymph node metastasis in a 17-year-old boy.
A case of duodenal gangliocytic paraganglioma (DGP) in a 17-year-old boy is presented. In this case a lymph node in the peripancreatic region was involved by a metastatic tumor. A review of the literature on DGP indicates that this case represents the youngest patient and is the second case of DGP with metastasis. Immunohistochemical staining for neuron-specific enolase (NSE), neurofilament (NF), pancreatic polypeptide, and somatostatin showed positive results for epithelioid and ganglion-like cells, whereas spindle cells showed immunoreactivities for S-100 protein, NSE, and NF. The histogenesis of DGP is discussed.
