title: The cytologic diagnosis of gangliocytic paraganglioma: a case report.
abstract: Gangliocytic paragangliomas are rare tumors primarily found in the duodenum. We report a case of a woman who presented with a retroperitoneal lymph node involved by metastatic gangliocytic paraganglioma. Subsequently, fine-needle aspiration (FNA) cytology was used to identify the primary duodenal gangliocytic paraganglioma. The smears of the aspirate material were highly cellular and contained a dominant population of epithelioid cells, a second population of ganglion cells and a third population of small, bland spindled cells. To our knowledge, the cytologic features of gangliocytic paraganglioma have not previously been documented.
