Intraorally , the swelling extended from distal aspect of right lower canine to the right lower second molar , measuring about 3 * 2.5cm ( Fig . 2 ).

It had well defined margins , expanded buccal cortex but no soft tissue perforation . Radiographic evaluation consisted of panoramic radiograph ( OPG ), non contrast computed tomography ( CT ) with 3 D reconstruction of the face . OPG showed a multilocular radiolucency with diffuse , scattered radio-opacities extending from the lower right canine to the ascending ramus , giving a trabeculated ‘ honey comb appearance ’. There was resorption of the distal root of the second molar . This lesion was found to be associated with an inverted impacted lower third molar ( Fig . 3 ).
Fig 5 There was destruction of the cortex and buccal perforation in the premolar molar region . ( Fig . 6 )

CT scan revealed an expansile mass of right side of mandible with expansion of both buccal and lingual cortices ( Fig . 4 & 5 ).
Tentative differentials included ameloblastic fibroma and a fibro-osseous lesion . An incisional biopsy was taken from the involved region and sent for histopathological examination ( HPE ). HPE revealed polyhedral epithelial cells arranged in sheets and anastomosing large and small islands interspersed by prominent homogenous hyaline acellular material .
