Keratocystic odontogenic tumor (KCOT) formerly known as odontogenic keratocyst (OKC), is considered a benign unicystic or multicystic intraosseous neoplasm and one of the most aggressive odontogenic lesions presenting relatively high recurrence rate and a tendency to invade adjacent tissue. On the other hand Dentigerous cyst (DC) is one of the most common odontogenic cysts of the jaws and rarely recurs. They were very similar in clinical and radiographic characteristics. In our case a pathological report following incisional biopsy turned out to be dentigerous cyst and later as Keratocystic odontogenic tumour following total excision. The treatment was chosen in order to prevent any pathological fracture. A recurrence was noticed after 2 months following which the lesion was surgically enucleated. At 2-years of follow-up, patient showed no recurrence.
