FIRST PARAGRAPH: Keratocystic odontogenic tumor (KCOT; formerly known as odontogenic keratocyst) is a distinct developmental odontogenic cyst that may be locally aggressive and may be part of the nevoid basal cell carcinoma syndrome (NBCCS, or Gorlin syndrome). Inherited as an autosomal dominant trait, there is high penetrance, although with variable expression, associated with loss of function of the PTCH gene (chromosome 9q22.3-q31), a tumor suppressor gene.
