Solitary fibrous tumor of maxilla: A rare entity.

Solitary fibrous tumor (SFT) is a ubiquitous rare mesenchymal neoplasm. Pleura is the favored site of origin and is rare in the oral cavity. SFT occurs across a wide histopathologic spectrum. Fibrous form characterized by hyalinized, thick-walled vessels with opened lumina and strong CD34 reactivity constitute one end and on the other end, a cellular form representing the conventional hemangiopericytoma, with branched, thin-walled vessels and focal or negative CD34 reactivity characterize the spectrum. A case of oral SFT in a 30-year-old female patient with its clinical, histopathological and immunohistochemical features is being presented here.
