Ameloblastoma
Image Description
Image showing squamous metaplasia in ameloblastoma. In some cases, squamous metaplasia is quite extensive and squamous cell carcinoma needs to be excluded. Lack of cytologic atypia is a helpful clue to the correct diagnosis. Ameloblastoma is a locally aggressive tumor and is considered to be a borderline (low-grade malignant) tumor. Distant metastases may occur in rare cases.
