Calcifying cystic odontogenic tumor (CCOT) is a rare odontogenic cyst accounts for <2% of all odontogenic cysts. Simple unicystic CCOT is commonly encountered accounts for 65%, whereas other forms of CCOT are <3%. CCOT is associated with two or more odontogenic tumors, it is called combined odontogenic lesions or hybrid lesions. The aim of the present article is to report a rare case of CCOT and highlighting the clinical feature and treatment aspects of combined lesions. A 25-year-old female complained of pain and swelling in the left maxilla for 6 months. Examination revealed diffuse swelling in the maxilla, firm in consistency, and tender on palpation. Panoramic radiograph showed impacted canine with multiple radiopaque structures and well-defined lesion in the maxillary sinus. The lesion was surgically removed and histopathologically diagnosed as CCOT with compound odontoma and ameloblastoma. Pub Med database search from 1978 to June 2020 revealed only three case reports of combined odontogenic tumors associated with CCOT.
