On extraoral examination, we observed a single extraoral nontender swelling about 5 x 5 cm in size [Figure 1].
Case 1. 50-year-old female with a huge swelling in the left cheek diagnosed with unicystic ameloblastoma. a) Panoramic radiograph shows well-defined periradicular radiolucency (dashed arrow) in the left maxillary region in relation to carious tooth (root stump) 27 (white arrow). b) Postoperative view shows the area from where the cyst was enucleated. c) Photograph shows the excised tissues.

After enlarging the bony access, the entire cyst was enucleated by performing curettage of the lesion in both the cases [Figure 2b]. The excised specimens were then submitted for histopathological examination [Figures 2c and 3b].

Case 2. 34-year-old female patient with complaints of pain and swelling in the back upper right tooth diagnosed with unicystic ameloblastoma. a) Panoramic radiograph shows well-defined periradicular radiolucency (white arrow) in the right maxillary region in relation to carious (root stump) 17 (dashed arrow). b) Photograph shows excised tissue.

Orthopantomograph (OPG) showed radiolucency of size 5 x 5 cm extending from tooth 11 to tooth 17 and to the periapical region giving a cystic appearance [Figure 3a]. The excised specimens were then submitted for histopathological examination [Figures 2c and 3b].
Case 1. Hematoxylin and eosin stained section shows degenerating stellate cells (white arrow) along with ameloblastic epithelium (dashed arrow) (x40).

Histologically, in both the cases the cyst lining showed ameloblastic epithelium with tall columnar basal layer, subnuclear vacuoles, reverse nuclear polarity and thin layer of edematous, degenerate-appearing stellate cells [Figure 4].
Case 2. Hematoxylin and eosin stained section shows cystic lining epithelium with proliferation and archading epithelium (black arrow) (x40).

In case 2, the cystic lining epithelium also demonstrated rete ridges in some areas with proliferation and archading epithelium mimicking a radicular cyst [Figure 5].
