Histopathological examination of acanthomatous ameloblastoma shows squamous metaplasia of stellate reticulum and the formation of keratin within the tumor islands .
Our case report has various significant features which discerned it from previously reported cases of acanthomatous ameloblastoma. The case being discussed is presented with a diffuse swelling involving complete ramus of the mandible in a 12-year-old boy.

in dogs treated with intralesional bleomycin.
Here we report a rare case of acanthomatous ameloblastoma with surface epithelium showing verrucous changes in 55 year old healthy female with mild swelling in left lower anterior jaw between canine and premolar area.
Thus, after histopathological evaluation a final diagnosis as acanthomatous ameloblastoma with verrucous epithelial proliferation was made.
Acanthomatous ameloblastoma is a rare variant with distinctive features which accounts for 12.1% of cases.
CONCLUSIONS: Acanthomatous Ameloblastoma is a very rare tumor.
