Keratocyst is a development odontogenic cyst, because of their specific histopathology features, aggressive biological behavior and a high degree of recurrence. The most common site is the body KCOT posterior mandible and ramus. KCOT shows a well-defined radiolucent area with sclerotic margins smooth and often while a large lesion may appear multilocular. Treatment may be conservative such as enucleation (with or without curettage), the decompression and marsupialization or aggressive treatments including peripheral ostectomy with rotary instruments, cryotherapy with liquid nitrogenand application of Carnoy's fixative and jaw resection. The eradication of the cyst and the reduction of risk of recurrence and morbidity of surgery are the main objectives of all techniques. We report a case of KCTO located in anterior maxilla in a male patient of 26 years old, which is sent to the service of Stomatology and Oral Surgery, University of Cartagena.
