Odontogenic keratocyst of mandible with an unusual presentation – A case report

Odontogenic keratocysts (OKCs) are developmental odontogenic cysts of epithelial origin with aggressive behavior and a high recurrence rate. OKC can be formed in place of tooth, embrace the unerupted tooth, present in ascending ramous or present between roots of the teeth. OKC generally tends to grow in an anteroposterior direction within the medullary cavity of the bone without causing obvious bone expansion but in this case there was a large extra oral swelling along with extra oral sinus present. Hence OKC can be mistaken for any other cyst and tumour.
