Acanthomatous Ameloblastoma of Mandible: A Rare Clinical Presentation

Ameloblastoma is a benign locally aggressive infiltrative odontogenic tumour commonly located in the jaw bone. Patients with this tumor usually presents in late stages with facial disfigurement caused by expansion of the jaw bones. The most common site of involvement is mandibular third molar region. Among the histological variants, acanthomatous ameloblastoma is the rarest of all. It may pose a diagnostic challenge when ameloblastoma manifests as a small alveolar swelling in the anterior region of jaws without any distinct features. Here we are reporting such a case of 44-year-old male with a small swelling on right anterior mandible region which was diagnosed as acanthomatous ameloblastoma based on clinical, radiographic and histopathological features.
