case_images: Osteolytic lesion (arrows) with well-defined limits in relation to proximity to the pericoronal follicle of tooth #38. Note the expansion and destruction of the lingual cortical bone of the mandible. (A) Panoramic and parasagittal reconstruction; (B) sagittal and axial reconstructions.

case_images: The lesion showed expansion and destruction of the lingual cortical bone of the mandible (Figures 1(A) and 1(B)).
case_images: Histological and immunohistochemical features. HE staining revealed a nonencapsulated neoplasm of glandular epithelial origin (A-D). The tumor was comprised with mucous, intermediate, and squamous cells, with cystic growth patterns in some areas (asterisks) (E, F). A large amount of mucus was seen throughout the neoplasm. Mucous cells were positive for PAS with diastase digestion (G). Neoplastic cells were positive for cytokeratin (CK) 7 (H) and CK14 (J) and negative for CK13 (I). Objetives: (A) 1x, (B) 2x, (C) 4x, (E, H) 10x, (F, G) 20x, and (I, J) 40x.

case_images: A large amount of mucous was seen throughout the neoplasm (Figures 2(A)-2(F)). In the histochemical staining with periodic acid-Schiff (PAS) with diastase digestion and mucin staining, the presence of mucous cells was observed (Figure 2(G)). The cytokeratin 13 and Ki-67 expression was negative (Figures 2(H)-2(J)).
