Abstract

Intraosseous ameloblastoma is the most common and simple type of ameloblastoma prevalent among odontogenic tumors. Clinico-radiographically intraosseous ameloblastoma presents as slow, painless swelling or expansion of the jaws and described as multilocular expansile radiolucency that occurs most frequently in mandibular molar/ramus area. This article describes a case of follicular ameloblastoma involving 45 year old male which is different from the usual presentation, which includes-exophytic growth, different location and without expansion of the cortex.

Figure

• 

  Fig. 1 Clinical photographs show an exophytic growth at the inter-dental area in right mandible between canine and first premolar extending labially (A) from the attached gingiva of the teeth to the lingual sulcus of incisors, canine, and first premolar teeth (B).

• 

  Fig. 2 Intraoral periapical radiograph shows a presence of characteristic soap bubble appearance in the region of the right mandibular canine and first premolar, and knife edge root resorption pattern in relation to the first premolar.

• 

  Fig. 3 Panoramic radiograph shows a radiolucent area measuring 4×4 cm in diameter extending from the distal aspect of the right lateral incisor to the mesial aspect of the second premolar.

• 

  Fig. 4 Occlusal radiograph shows no cortical expansion.

• 

  Fig. 5 Gross specimen after surgical removal.

• 

  Fig. 6 Histopathological examination demonstrates connective tissue with numerous follicles lined by single layer of tall columnar ameloblast-like cells (H&E stain, 40×).
