RESUMO
Ameloblastoma is a benign, locally aggressive tumor originating from the odontogenic epithelium. It manifests as a slow growing swelling, causing expansion of the jaw bones. Radiologically, it presents as a unilocular or multilocular radiolucency exhibiting a characteristic soap bubble or honeycomb appearance. Ameloblastoma exhibits several histologic patterns of which basal cell variant is a rare entity. The present case report is that of a maxillary ameloblastoma exhibiting a basaloid differentiation that may put one in the mind of a basaloid squamous cell carcinoma or a basal cell carcinoma. Confirmation of such rare variants should be done not only based on histopathology but with the help of supplemental immunohistochemical analysis. The present case report helps in exposing a rare variant of ameloblastoma and emphasizes the role of advanced diagnostic aids such as immunohistochemistry in establishing the diagnosis.
