A case of sinonasal paraganglioma with a different morphology: nine-year follow-up.

Paragangliomas are very occasionally located in the nasal cavity. In this article, we present a 32-year-old female case with a sinonasal paraganglioma with atypical histopathological morphology. In our case, sinonasal paraganglioma consisted of lipoblast-like vacuolated cells instead of the typical Zellballan histological pattern. The prognosis of a nasal paraganglioma is not very clear. The present article is important, as it describes the first case report of a sinonasal paraganglioma with atypical lipoblast-like vacuolated cells with a nine-year follow-up.
