The term ‘hybrid ameloblastoma’ was introduced by Waldron and el-Mofty in 1987, and was discovered as a rare histopathological variant including a combination of the classical follicular or plexiform type along with areas of desmoplastic type. As per the current literature, hybrid ameloblastoma accounts for 1.1%–4.3% of all ameloblastomas. Imaging plays an inevitable role in diagnosis, treatment planning, and assessment of disease progression and prognosis. Depending on the type of ameloblastoma, imaging features vary from unilocular to multilocular lesions, with a characteristic ‘soap bubble’ or ‘honey comb’-like appearance. Three-dimensional imaging modalities like cone beam computed tomography (CBCT) are considered a standard today due to their superiority over the conventional radiographic techniques.
Treatment includes both conservative and radical modalities and purely depends on case selection and the variant of the tumour. Complete surgical removal of the tumour and restoration of function and appearance are the main goal of therapy. The most common treatment modality advocated is resection. Extensive lesions are treated by wide resection with 1 cm margin. But, if the case is not severe, a conservative approach like enucleation and curettage is followed, so as to preserve the integrity of the anatomical structure and prevent disfigurement.
In this poster, we report a case of hybrid ameloblastoma of the mandible with distinct clinical, radiologic, and histopathologic findings in a geriatric male patient. The imaging analysis was done using panoramic radiographs under conventional radiography and cone beam computed tomography (CBCT) scans under advanced imaging modalities. The diagnosis was confirmed with incisional biopsy and the patient was planned for surgical resection with a margin of normal bone.
