Abstract

Gangliocytic paraganglioma is a rare tumor that is usually seen in the duodenum. This neoplasm generally behaves in a benign fashion, although instances of recurrence and lymph node metastasis have been described. We experienced a case of incidentally found gangliocytic paraganglioma treated with endoscopic resection. A 61-year-old man was referred because of submucosal tumor adjacent to the major papilla. Endoscopic biopsy revealed paraganglioma. Abdominal CT showed that there was no evidence of a duodenal mass or lymphadenopathy. This tumor was resected endoscopically by electrosurgical snare polypectomy. The excised tumor measured 1.0 cm in diameter. Histopathological examination revealed a benign gangliocytic paraganglioma and the resection margins were free of tumor. At the 6-month follow-up, the patient was still asymptomatic and no residual tumor was detected at the resection site.
