Two cases of solitary fibrous tumors arising in the buccal region

Solitary fibrous tumors (SFTs) are mesenchymal neoplasms. Although they are most frequently located in the pleura, they have also been observed in other locations. We report two cases of SFTs in the buccal region of a 78-year-old man and 56-year-old woman, respectively. The chief complaint of both patients was a swelling of the buccal space. Each patient underwent surgical excision after receiving a clinical diagnosis of a buccal tumor. We obtained a definitive diagnosis in the female patient, but the tumor decreased in size after the biopsy. The histopathological characteristics of both tumors included proliferating spindle cells and thin-walled, branching, staghorn-like vascular patterns.
