Microscopic examination showed numerous lobules with basophilic cells in the periphery and of ghost-like squamous cells toward the center with a few anucleated cells [Figure 2]. There were numerous foci of calcification more so in the necrotic areas and in the periphery of cellular islands [Figures 2 and 3].

Various stages of maturation of the basaloid cells into shadow cells could be seen [Figure 3]. There were numerous foci of calcification more so in the necrotic areas and in the periphery of cellular islands [Figures 2 and 3].
