Abstract:
A case of gangliocytic paraganglioma of the second portion of the duodenal loop is presented. The tumor was polypoid and, histologically, composed of mature ganglion cells, spindle cells and epithelial-like cells. Immunocytochemical examination demonstrated the presence of neurofilament 200 K and S-100 protein only in the first two types of cells; all the cells were positive for neuron-specific enolase. The reaction for cytokeratin was negative in all neoplastic components. According to morphologic and immunocytochemical findings, we suggest a hamartomatous nature of this entity.
