Duodenal gangliocytic paraganglioma with lymph node metastases : a case report and review of literature

Duodenal gangliocytic paraganglioma is an extremely rare tumor. The part of the rare place is esophagus, jejunum, pylorus, pancreas and upper mediastinum. Though considered benign the disease can spread to regional lymphatics. Gangliocytic paraganglioma is a rare tumor that is located in the duodenum in 90% of cases and has been regarded as benign in general with a favorable prognosis. Local excision is used to treat the disease, and radical surgery and lymph node dissection can be avoided if gangliocytic paraganglioma is confirmed. Now, we report a 65-year-old man with lymph gland metastases of duodenal gangliocytic paraganglioma. Local resection was performed. Gangliocytic paragangliomas (GPs) are rare tumors of the duodenum and demonstrates low malignant potential.
