Keratoameloblastoma is a rare variant and histologically heterogenous group of ameloblastomas,
which have areas of ameloblastic epithelium and extensive keratin formation. Other subtypes of
ameloblastoma which exhibit keratinisation in their parenchyma include acanthomatousameloblastoma, and
papilliferouskeratoameloblastoma. Previously it was thought to be a variant of acanthomatousameloblastoma
with focal areas of keratinisation. Extensive keratin deposition in the connective tissue isolates
keratoameloblastoma as a separate entity from acanthomatousameloblastoma. The tumour presents itself as
a destructive and an enlarging mass, mostly involving the posterior region of the mandible, with men being
more commonly affected in the ratio of 3:1. This case report presents two cases of keratoameloblastoma, one
in the posterior mandible and the other in the anterior maxillary region.
