# All are features of Keratocystic odontogenic tumor EXCEPT:

A. Most common location is the posterior body of the mandible

B. Shows evidence of a cortical border, when not secondarily infected

C. Internal structure is most commonly radiopaque

D. Curved internal septa may be present

The correct answer is C. Internal structure is most commonly radioopaque.

Keratocystic odontogenic tumors (KCOTs) are benign but locally aggressive lesions. Their radiographic appearance is typically:

Radiolucent: KCOTs appear as dark areas on radiographs, indicating that they are less dense than the surrounding bone.

Well-defined borders: They usually have clear and distinct margins.

Unilocular or multilocular: They can be single-chambered (unilocular) or multi-chambered (multilocular).

Scalloped borders: The edges of the lesion may have a wavy or scalloped appearance.

Curved septa: If multilocular, the internal septa may appear curved.
