Duodenal gangliocytic paraganglioma (DGP) belongs to a subclass of neuroendocrine neoplasms, characterized with unique histologic features of carcinoid tumor, paraganglioma and ganglioneuromas. According to the recent World Health Organization classification of gastrointestinal neuroendocrine tumors (NETs), there is a debate to classify them either as low-grade NETs or as an independent entity. There are a few reports of regional lymph node (LN) metastasis that could argue DGP as a true neoplasm. However, majority of them had a benign course, raising the question of whether long-term follow-up is required. We report a case of a retroperitoneal LN involvement by metastatic GP and additionally performed a systematic review of the literature to determine the optimal follow-up, since no guidelines exist for this rare entity.<\/jats:p>","DOI":"10.1093\/jscr\/rjab159","type":"journal-article","created":{"date-parts":[[2021,4,6]],"date-time":"2021-04-06T11:11:27Z","timestamp":1617707487000},"source":"Crossref","is-referenced-by-count":4,"title":["Prognosis
