Keratocystic Odontogenic Tumor with an Ectopic Tooth in Maxilla

الملخص EN

The term odontogenic keratocyst was first used by Philipsen in the year 1956.

The lesion was renamed by him as keratocystic odontogenic tumor (KCOT) and reclassified as odontogenic neoplasm in the World Health Organization’s 2005 edition that occurs commonly in the jaws having a predilection for the angle and ascending ramus of mandible.

In contrast, KCOTs arising in the maxillary premolar region are relatively rare.

Here, we discuss a rare case of keratocystic odontogenic tumor occurring in the maxilla with an ectopic tooth position.
