Gross examination of the specimen revealed a firm and oval mass with cystic aspect, containing liquid in the interior (Figures 2(a) and 2(b)).
(a) Photomicrography showing a cystic lesion with a fibrous capsule and a lining of odontogenic epithelium (H/E, 40x). (b-c) Highlight for the columnar basal cells of similar to ameloblasts and the overlying layers loosely arranged with several amounts of ghost cells (H/E, 200x). (d-f) Extensive areas of eosinophilic matrix compatible with dentinoid within the fibrous capsule adjacent to odontogenic epithelium (H/E, 200x, 400x).

Microscopically, the hematoxylin and eosin (H and E) stained section showed a defined cystic lesion with a fibrous capsule and a lining of odontogenic epithelium (Figures 3(a)-3(c)). Several amounts of ghost cells were found within the epithelial component and also in the capsule (Figure 3(c)). Extensive areas of eosinophilic matrix compatible with dysplastic dentin (dentinoid) were found in the fibrous capsule (Figures 3(d)-3(f)).
