Diagnosis of solitary fibrous tumor in the submandibular gland: Case report and literature review

Solitary fibrous tumors (SFTs) rarely occur in the head and neck area. Imaging findings are nonspecific, and immunohistochemical (IHC) analysis is necessary for a definitive diagnosis. We report the case of a patient with a mass in the submandibular region that was initially diagnosed as basal cell adenoma. After excision and IHC examinations, a SFT was diagnosed.
