case_images: After that, the tumor mass and the unerupted canine were removed (Figure 1a), and finally we repositioned the tissue and sutured the mucoperiosteal flap. After routine histology on the material, under light microscopy they observed fragments of the odontogenic lesion, characterized by the proliferation of fusiform/globular cells, arranged as large islands and solid sheets, as well as numerous structures similar to ducts, lined by low cylindrical or cubic cells, of polarized nuclei (Figure 1b). Occasionally, some detached eosinophylic amorphous material was, together with calcification areas (Figure 1c). We also noticed the presence of a cystic lesion coated by a stratified pavement epithelium, formed by few cell layers (Figure 1d), showing a continuity with the neoplastic foci aforementioned, and a connective fibrous capsule.
