Giant Cell Angiofibroma in the Buccal Mucosa – A Rising Entity?

Abstract

Background: Tumors of the oral cavity must be differentiated into benign and malignant. Rare tumors must also be considered throughout the differential diagnosis when dealing with pathologic changes in the oral mucosa. Examples of rare benign tumors within the oral cavity are solitary fibrous tumors (SFTs). In recent years, individual case reports of SFTs in the oral cavity have been published showing a rising incidence of this rare entity. Case Report: The present case report describes the occurrence of a subtype of SFT in the right buccal mucosa, the so-called giant cell angiofibroma (GCA). Histopathologically, GCA are distinguishable from SFT (NOS) by pseudovascular spaces lined by multinucleated giant cells. GCA generally shows a benign tumor behavior. The treatment of choice was surgical excision through an intraoral approach. Conclusion: To the best of our knowledge, this is one of a few reports of GCA arising in the buccal mucosa.
