case_images: Clinical examination disclosed a swelling measuring about 5 mm in diameter in the region of lower left premolars which was non tender, and the over lying mucosa was normal in color. Clinically, a provisional diagnosis of epulis was made (Figure 1).
case_images: Solid wellcircumscribed encapsulated mass (a) showing ameloblastomatous islands of odontogenic epithelium (b) and ghost cells (c) with overlying epithelium (d) [Hematoxylin and Eosin, x4].

case_images: fig2
case_images: Histological examination revealed a solid well-circumscribed, encapsulated soft tissue mass surrounded by a dense fibrous connective tissue covered by stratified squamous epithelium (Figure 2).
case_images: Ameloblastomatous island of odontogenic epithelium with columnar basal cells (a) enclosing stellate reticulum like cells (b) [Hemataoxylin and Eosin, x40].

case_images: fig3
case_images: The tumor mass revealed islands of odontogenic epithelium resembling follicles of ameloblastoma, consisting of columnar cells enclosing stellate reticulum like cells (Figure 3).
case_images: Ghost cells (a) and surrounding dentinoid-like material (b) [Hemataoxylin and Eosin, x20].

case_images: These elements were associated with numerous pale, eosinophilic ghost cells with granular eosinophilic cytoplasm and faint nuclear outline (Figure 4).
case_images: Irregular foci of dentine/osteo-dentine-like material (a) and calcifying ghost cells (b) and giant cells (c) [Hemataoxylin and Eosin, x40].

case_images: fig5
case_images: Irregular foci of tissue resembling dentin were observed surrounding the odontogenic epithelial islands, and these areas were atubular and at places showed cellular inclusions (Figure 5).
case_images: Van Gieson stains showing ghost cells staining yellow (a) and surrounding dentinoid-like material staining pink (b) [Van Gieson stain, x40].
