Introduction: The Stafne bone defect (SBD) is described as a well-defined, unilateral radiolucent area, usually in the region close to the angle of the mandible and below the mandibular canal. This asymptomatic condition, diagnosed in routine radiographic examinations, affects males between the 5th and 7th decade of life and does not require surgical intervention. The etiology of the condition is uncertain; however, the occurrence of SBD is often associated with salivary gland hypertrophy/hyperplasia. Case presentation: On this report, we present a case of SBD, the posterior variant, exhibiting uncommon dimensions. Conclusion: The Stafne bone defect is most often the result of failure of mandibular ossification
