The spindled structures, where the duct-like and adenomatoid structures were located, would form a cell group analogous to post-secretory ameloblasts of the reduced enamel epithelium, surrounded by a second group, constituted by flat fusiform cells, sometimes with morphology similar to that of the stellate reticulum.

We could justify the absence of the typical adenomatoid structures in the solid nodules forming sheets because they could have disappeared for having been gradually compressed by the tumoral mass as it evolved.
