Odontogenesis keratocyst is a histological type of developmental odontogenic cysts whose incidence occurring between the second and the third decades of life with a potential second appearance in fifth decade. The lower third molars and the mandibular angle areas are the more involved and from there the lesion progresses to branch and body. Among the other types of cysts this is very important due to the high rate of relapse located between the 25 and the 60 % and by its histopathologic features differentiating it from other cystic lesions. The case of a female aged 33 is presented, which in clinical and radiographic examination had a lesion circumscribed to radiolucent unilocular left mandibular area in the second premolar eruption. After clinical radiographic and histopathologic examinations an odontogenic keratocyst was diagnosed. Surgical treatment was applied with satisfactory results and until now without clinical and radiographic relapse signals.
