Resumo (EN)
Cysts are benign odontogenic lesions which can reach large dimensions and most common in jaws. Despite the slow growth and continued characterize any type of cyst, the odontogenic keratocyst calls attention for being more aggressive and highly recurrent (the recurrence rate varies from 22% to 60%). The age of occurrence of the keratocyst is wide and impossible to determine, with no preference regarding gender of the patient. Its typical location is the posterior mandible, including angle and ramus. Radiographicaly is radiolucent and well defined. The pattern unilocular predominates over the standard multilocular. The keratocyst or odontogenic keratocyst is currently considered an odontogenic tumor, due to its aggressiveness, growth potential, neoplastic nature and high recurrence rate. Therefore, the correct name and current for this lesion is Keratocystic OdontogenicTumour.
