ABSTRACT: Background: Hybrid
Ameloblastoma is a rare type of ameloblastoma that is presently receiving
attention in some quarters. Altogether, less than 30 cases have been reported
in the scientific literature, thus calling for the need to report more cases in
order to add to the body of knowledge on this lesion. This case report is aimed
to add to the number of cases that are building up in the scientific
literature. Materials and Methods: A 50-year-old female presented with a 3-year
history of an anterior mandibular swelling extending from the body of the
mandible on the right to the body of the mandible on the left. Orthopantomograph
of the lesion revealed a mixed radiolucent and radiopaque lesion that extended
from the distal region of the right mandibular second premolar to distal region
of the left mandibular second molar. Segmental mandibulectomy with immediate
replacement with reconstruction was undertaken. Results: Specimen which was
subjected to histopathologic examination reported a diagnosis of Keratinizing
Follicular Ameloblastoma and Desmoplastic
Ameloblastoma with Osteoplasia, consistent with a diagnosis of Hybrid Ameloblastoma.
There has been no sign of recurrence 7 months after a regular follow-up and the
patient is planned for a long term follow-up. Conclusion: Besides histological
details that combine both conventional ameloblastoma and desmoplastic ameloblastoma,
the present case of hybrid ameloblastoma bears similar clinical features as
well as treatment modalities to that of conventional solid multicystic ameloblastoma.
