Histopathological examination of partially decalcified tissue with hematoxylin and eosin stain revealed well-encapsulated mass with peripheral areas showing interconnected odontogenic islands with tall columnar to cuboidal cells with polarized hyperchromatic nucleus at periphery with central stellate reticulum like areas, merging with sheets of closely packed ovoid to spindle cells interspersed with abundant amounts of an eosinophilic homogeneous extracellular material representing dentinoid or osteodentin is evident [Figures 6 and 7].
