[A case of duodenal gangliocytic paraganglioma with lymph node metastasis].
A 28-year-old man complained of tarry stool. A series of examinations showed a submucosal tumor with bleeding at the papilla of Vater and a swollen # 17b lymph node, both of which indicated a hypervascular tumor. The pathological findings of the enucleated tumor specimens revealed gangliocytic paraganglioma with metastasis to the # 17b lymph node. Additional pancreaticoduodenectomy revealed another # 17b lymph node metastasis 7-mm in diameter. Although the majority of gangliocytic paragangliomas are benign, 7% of reported cases have lymph node metastases, as shown in the present case. These findings are important in treating patients with gangliocytic paraganglioma.
