Granular Cell Ameloblastoma: A Rare Threat Requiring Vigilance and Lifelong Follow-Up.

This case report describes a 45-year-old male who presented with mobility and dull pain in the lower right back tooth region for two months. Initially diagnosed with localized periodontitis at a private clinic, the patient sought a second opinion. Clinical examination revealed slight obliteration of the buccal vestibule and mobility in teeth 45 and 46. Radiographic findings showed a unilocular radiolucency in the periapical region of the premolar and first molar. This case highlights the importance of including granular cell ameloblastoma in the differential diagnosis of mandibular lesions and stresses the need for thorough clinical and radiographic evaluation to avoid misdiagnosis and ensure proper treatment.
