Abstract
We reviewed 30 cases of keratocystic odontogenic tumor (KCOT) managed during the 8-year period between 2001 and 2008. This case report described the clinical, radiographic and histopathologic features of these KCOT. Of the 30 patients in whom KCOTs were diagnosed, 18 (60%) of the patients were male and 12 (40%) were female. The mean age of these patients was 34.2 years, with peak incidence occurring in the third decade of life. The lesions were mostly located in the mandible (74.2%) and in the maxilla (25.8%). There was a marked predilection to occur in the posterior mandible. Radiographically, 19 (63%) out of the 30 cases were unilocular type with a well demarcated border, while 11 cases (37%) were multilocular in appearance. Histopathologically, 73% of the cysts were lined with parakeratinized stratified squamous epithelium, while only 3% of the cysts were lined with mixed parakeratinized of orthokeratinized epithelium. 22 cases (73%) contained keratin in the lumen. A satellite cyst was observed in 14 cases (47%). All cysts were treated by enucleation. The recurrence rate was shown as 10% for 3 patients with a follow up period and recurred lesions were treated by re-enucleation.
