Management of keratocystic odontogenic tumour with marsupialisation, enucleation and Carnoy's solution application: a case report.

The keratocystic odontogenic tumour (KCOT) is a relatively common oral and maxillofacial lesion that derives from remnants of the dental lamina. It is aggressive, grows rapidly and invades the surrounding tissues. Various treatment modalities and differing recurrence rates have been reported for KCOT. In order to treat a 24-year-old male patient with KCOT the first stage was marsupialisation. This was followed six months later by enucleation with the application of Carnoy's solution. The defect was filled completely with newly formed bone tissue after two years. This case shows that a large KCOT can be treated with a combination of conservative and aggressive methods.
