[Ganglioneuroma of parapharyngeal space: case report and review of the literature].
A case of ganglioneuroma of parapharyngeal space is described and the literature on this field is briefly reviewed. The patient, a 7-year-old female, presented with a left parapharyngeal space mass causing medial displacement of the left lateral pharyngeal wall. The lesion sized 4.4 cm in the largest diameter. Histologically, the tumour showed the coexistence of two distinct cells types--ganglion cells and Schwann cells--within a loose stroma. Immunohistochemically, both cell types were immunoreactive for S-100 protein and negative for cytokeratins.
