Keratoameloblastoma: a case report and a review of the literature on its radiologic features.
Keratoameloblastoma is a rare subtype of ameloblastoma. It tends to have a poor prognosis, and therefore a careful diagnosis based on imaging is important in planning appropriate surgical treatment for this distinctive type of ameloblastoma. A unique feature of keratoameloblastoma is atypical calcification inside the mass, such as a ground-glass appearance, internal calcification, or a mixed radiolucent and radiopaque pattern. Because of its poor prognosis and the likelihood of frequent recurrences, surgical resection is considered the treatment of choice. This study reports a new case of keratoameloblastoma with special emphasis on its radiologic features and reviews previously reported cases of keratoameloblastoma.
