Keratocystic Odontogenic Tumor of Maxilla Mimicking Radicular Cyst.

ABSTRACT

Odontogenic keratocyst was the first illustrated by Phillipsen in 1956 and is unique as it is aggressive locally, and rate of recurrence is high along with histological appearance which is very characteristic. It is a benign neoplasm of jaw with the diverse origin and its occurrence in maxilla is uncommon. We present a case of 30-year-old male with aggressive keratocystic odontogenic tumor (KCOT) in the right maxillary molar region. On radiological examination, radiolucent area, mimicking radicular cyst, was found in relation with maxillary first molar. A final diagnosis of KCOT was confirmed after histopathological findings. The clinical, radiological, and histopathological features of this tumor along with surgical management have been discussed.
