“…KCOT has been shown to have a bimodal age distribution with first peak in the second and third decades and the second peak in the fifth decade or later. It is said that the lesions in the second peak are more common in maxilla 1 4. But the present case does not follow this conventional norm regarding age and area specificity of the cyst.…”

SUMMARYKeratocystic odontogenic tumours are known for their peculiar behaviour, varied origin, debated development, unique tendency to recur and disputed treatment modalities. Thus, it has been the subject of much research over the last 40 years. It was formerly known as odontogenic keratocyst (OKC). OKC received its new title as keratocystic odontogenic tumour (KCOT) by the WHO (2005) in order to suggest its aggressive and recurrent nature. KCOT is a benign intraosseous neoplasm of the jaw. Involvement of the maxillary sinus is an unusual presentation. We present the case of an 11-year-old child with extensive KCOT and an impacted canine in the right maxillary sinus. The cyst was initially misdiagnosed to be a dentigerous cyst based on the clinical and radiographic features though a differential diagnosis of KCOT and adenomatoid odontogenic tumour was made. The histological examination of the specimen finally confirmed it to be a KCOT. The clinical, radiological and histological features of this tumour along with its surgical management have been discussed. BACKGROUND

“…[11,12] Maxillary KCOT tends to exhibit a smooth, round border while mandibular ones have scalloped border. In mandible, majority occur in third molar-ramus area, followed by first and second molar, and then followed by anterior mandible.…”

“…In maxilla, the most common site is the third molar area followed by the cuspid region. [11,12] The lesion may be single or multiple, the latter case being more common in patients with nevoid basal cell syndrome. Clinically, they are asymptomatic but may present as toothache, swelling, and bone destruction.…”

Keratocystic odontogenic tumor (KCOT) is a benign odontogenic tumor with a potentially aggressive and infiltrative behavior. In this article, we report a 22-year-old male patient with swelling over the right side of cheek and over the palate on the same side and orbital pain since two months. Medical history of the patient was not significant. Computed tomography scan showed a well-defined cystic mass occupying anterior and superior wall of maxilla from premolar region to the incisor region of opposite side and destruction of palate and inferior orbital wall. Cyst was excised via lateral rhinotomy incision completely with intact wall. Histopathological examination showed features of KCOT. Keratocystic odontogenic tumor is well-known for its tendency to recur, potential aggressive behavior, and defined histopathological feature. Keratocystic odontogenic tumor occurrence in the maxilla is unusual and its appearance in the maxillary sinus is very rare.

“…The keratocystic odontogenic tumor wall is usually thin unless there has been a superimposed inflammation [9, 10, 13, 14]. Characteristic features are

a parakeratinized surface which is typically corrugated, rippled, or wrinkled;

uniformity of thickness of epithelium ranging from 6 to 10 cells thick;

a prominent palisaded, polarized basal cell layer of cells having “picket fence” or “tomb stone” appearance.

Numerous surgical modalities have been suggested for the treatment of KCOTs, including enucleation with primary closure, enucleation with open packing, and resection with or without loss of jaw continuity.…”

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.
