Figures

Fig. 1
Fig. 1
a Unilocular radiolucency distal to the mandibular third molar. b Cystic lumen lined by epithelium of variable thickness is surrounded by fibrous wall. c Fibromyxoid wall lined by epithelium with basal cell extensions. Arrow indicates a deep-seated, whorled structure. d The lining epithelium is simple (upper), stratified (middle), and ameloblastomatous (below). Clear cells are scattered. e Intraluminal nodule containing globoid bodies of lightly basophilic material surrounded by a hyaline ring. H&E, original magnification ×40 (b), ×100 (c, e), ×200 (d)
Fig. 2
Fig. 2
a Irregular dentin and laminated enamel-like material (arrowhead) are formed at the luminal surface. Clusters of detached lining epithelium are floating within the cavity. Arrow indicates epithelial rests. b Fibrillar dentinoid and droplet calcifications in close proximity to clear epithelial rests (arrow). c High-power view of Fig. 1c (arrow) showing groups of calcified droplets and eosinophilic globules. Arrow indicates epithelial rests. d Small basophilic bodies identical to those seen in Fig. 1e become incorporated into an eosinophilic material. Arrow indicates epithelial rests. e Odontogenic fibroma-like proliferation. f Ameloblastic fibroma-like nodule. H&E, original magnification ×100 (a, f), ×200 (b–e)
Fig. 3
Fig. 3
a, b Mural deposits of osteodentin with calcification in unrelated dentigerous cysts. Arrow indicates mucous cells (b). H&E, original magnification ×200 (a, b)
