Abstract

Five-fluorouracil (5-FU) is an antimetabolite drug used in the treatment of various cancers, including basal cell carcinomas (BCC). Some authors believe that odontogenic keratocyst (OKC) would respond to 5-FU treatment because of their similarities to BCCs in molecular etiopathogenesis. The odontogenic keratocyst (OKC) is a developmental odontogenic cyst that arises from remnants of the dental lamina. A case of an OKC treated with 5-FU is presented in this study. A brown-skinned male, 61-year-old, sought an Oral and Maxillofacial Surgery service. During the clinical examination no mucosal changes, bone expansion or face asymmetry were observed. A panoramic radiography was performed and a unilocular radiolucent lesion was verified in the body and ascending mandibular ramus. The extraction of #17 and incisional biopsy were performed, and the diagnosis established was OKC, according to the histopathological patterns. Therefore, it was decided to perform a marsupialization and 5-FU intralesional. As a result, it could be observed exuberant bone neoformation, mainly in the basilar region of the mandible. Follow-up examination 4 months later showed no evidence of recurrence and the patient will be followed for at least another year so we can decide if another surgical procedure is necessary.
