Overlying mucosa was normal in appearance except for mucosa in relation to teeth number 33 to 35, which was ulcerated (Figure 1).
Orthopantomogram showing well-defined radiolucency with scalloped border.. Notes: Few areas showing multiple foci of radiopacity. There is obvious evidence of root resorption.

Orthopantomogram revealed a well-defined radiolucency with scalloped border extending from 37 to 46 (Figure 2).
Cystic capsule lined with epithelium composed of a well-defined basal layer of cuboidal cells with reversal of polarity.. Notes: The superficial cells resemble stellate reticulum. Ghost cells present within the epithelium lining as well as inside the connective capsule.
