CARNEIRO, Ariana Gonçalves et al. A year of decompression followed by enucleation for keratocystic odontogenic tumour's treatment: case report. RFO UPF [online]. 2012, vol.17, n.2, pp. 212-217. ISSN 1413-4012.

Introduction: the keratocystic odontogenic tumor (KOT), classified by WHO in 2005, belongs to the group of tumors originated from the odontogenic epithelium with no odontogenic ectomesenchyme included. It has aggressive behavior, however benign, with high frequence of recurrent cases, usually painless. It can affect patients of any age, with preference for male subjects, in the posterior mandibular region. Radiographically it can be present in either a unilocular or a multilocular form, which is often associated to the nevoid basal cell carcinoma syndrome (Gorlin-Goltz). Histologically, may present itself on two different types of epithelial lining, the orthokeratinized epithelium and the parakeratinized, being this last onethe most aggressive. Objective: There are several forms of treatment for KOT described in the literature; however, surgical removal is imperative. The purpose of this paper is to review the literature on KOT, including clinical features and therapeutic approaches, as well as to correlate this information with a non-syndromic clinical case. Case report: female patient, brunette skin, 25 years old, searched for medical care with an increase of volumes of hard consistency and without pain symptoms in the right mandibular body. The patient was treated with decompression of one year, surgical enucleation and peripheral ostectomy. Conclusion: The early choice of treatment for the keratocystic odontogenic tumor is the surgical enucleation, for extensive lesions may be used a previously adjuvant therapy, such as in decompression and marsupialization with peripheral ostectomy, which are simple to implement and have considerable result, providing patients a conservative and efficient treatment, and minimizing relapse.
