Unicystic ameloblastoma in a child: A case study and review of the literature

Panoramic radiograph at patient presentation showing a radiolucent lesion distal to the mandibular second right molar and displacing the third molar germ towards the inferior alveolar canal.

Panoramic radiograph of the patient taken two years earlier showing a well-limited radiolucent osteolytic lesion surrounding the crown of a lower right second molar.

Transversal CT scan reconstruction showing the lesion.

Ameloblastoma of luminal type showing columnar basal cells with prominent nuclear palisading and loosely arranged stellate, reticulum-like upper cellular layers. Hematoxylin–eosin–safran stain; original magnification 6.4×.

Ameloblastoma islands and strands within the connective tissue wall (mural invasion) with some follicles showing squamous metaplasia. Hematoxylin–eosin–safran stain; original magnification 20×.

Axial CT scan taken at 24 months follow-up demonstrating bone healing distal to the right second mandibular roots (a). Transversal CT scan reconstruction showing normal bone thickness of the right mandibular retromolar area (b).
