They showed a lytic lesion in the left posterior mandible, which appeared to be multilocular, in close association to the developing teeth and extending upwards into the posterior zygomatic arch, infra-temporal fossa as well as the orbital floor, causing resorption in these regions [Figures 1 and 2].

On reviewing the H&E-stained sections, a myxo-collagenous connective tissue stroma resembling the primitive DP, enveloped by a continuous thin layer of epithelium showing ameloblastomatous characteristics, was observed [Figure 3].
Higher magnification showing the ameloblastomatous characteristics of the lining epithelium - basal layer of tall columnar cells with reversal of polarity, resembling ameloblasts and upper layers loosely arranged cells; underlying dental papilla like stroma shows spindle cells dispersed within (H&E; 4a: 10x; 4b: 40x)

Moderate amount of vascularity was also noticed within this stroma [Figure 4].
