case_images: Microscopically, The lesional tissue contained variable-sized solid nodules of columnar cells of odontogenic epithelium forming nests and rosette-like structures (Figure 5(a)). The duct-like spaces were also seen and were lined by a single row of columnar epithelial cells, with the nuclei polarized away from luminal surface (Figure 5(b)).
