Neoplastic
- aka: basal cell carcinoma, acanthomatous ameloblastoma, acanthomatous epulis
- 18% of cases.
- Islands and sheets of mature odontogenic epithelium within a collagenous fibrous connective tissue stroma of low/moderate cellularity.
- Each of the islands bounded by a row of tall columnnar cells.
- These palisading cells exhibit polarisation away from the basement membrane and had cytoplasmic vacuolation.
- Central cells had a basaloid appearance.
- Often infiiltrating into the underlying bone.
- Synonymous with basal cell carcinoma.
