Moreover, other than scab in some areas, obliteration of the buccal vestibule, dental luxation in the involved area, no other pathological condition was found in intraoral examinations (Figure 1).

lesion in right posterior site of the maxilla extended to interradicular areas of
the regional teeth.

Microscopic findings showed a lesion which was partially covered by stratified squamous epithelial and composed of large number multinucleated osteoclast-like giant cells and mineralized tissue formation scattered within a fibroblastic and cellular vascular stroma including many plump spindle cells (Figure 4).
