In this article, we describe a case of ganglioneuroma observed in a 27-year-old woman. The tumor was found in an unusual location, the parapharyngeal space. The lesion was asymptomatic and was surgically excised after a fine-needle aspiration biopsy that was considered inadequate. The lesion measured 4 x 3 cm and was capsulated. Two distinct cells groups were identified: ganglion cells and Schwann cells placed in a loose myxoid stroma. Immunohistochemical stains (performed with the following monoclonal antibodies: high-molecular-weight cytokeratins, vimentin, neuron-specific enolase, neurofilaments, and S100) confirmed the diagnosis of ganglioneuroma. The pathologic findings and a review of recent literature are discussed.
