A rare presentation of stafne bone cyst.

Stafne bone cysts (SBC) are defined as pseudocysts of the jaw in the literature. These lesions are typically localized at lingual cortical surface of the mandible and generally included normal salivary gland tissue; but they do not contain an epithelial lining. They may contain fat, muscle, connective tissue, lymphatic tissue, nerve bundles, blood vessels or air. In the literature, unlike posterior variant of SBC, anterior type of SBC (aSBC) is almost seven times less common (0.009%-0.3%). Usually, SCBs are identified at dental examination randomly. Since these lesions are mostly asymptomatic, some additional imagining modalities such as magnetic resonance imaging (MRI), computed tomography (CT) or sialography may be useful to confirm the diagnosis for atypical lesions. The aim of this report is to present a new case of aSBC and focuses on differential diagnosis along with alternative diagnostic imaging resources and review current literature.
