하악 우측 우각부에 발생한 선종양 치계종양의 치험례

A case of adenomatoid odontogenic tumor occured in mandibular right angle portion

Adenomatoid odontogenic tumor (adenoameloblastoma) is a rare tumor that comprises only 0.1% of all tumors and cysts of the jaws and 3% of all odontogenic tumors. This tumor is generally considered to affect mainly patients in the second decade of life. It occurs with great frequency in females and is found most often in the maxilla and in the anterior region of the jaws. Encapsulation, duct-like structures containing eosinophilic hyaline material, spindled epithelium, cribriform pattern, intraluminal calcification and dystrophic calcification of degenerative connective tissue were common histologic features. We experienced a case of adenomatoid odontogenic tumor which occured in mandibular right angle portion of 17-year-old boy, associated with lower right second molar, and seemed to be showed pathologic fracture of the mandible. This lesion was treated with enucleation, fixation with mesh type titanium plate, and allograft with PYROST for aid of healing. No specific change has seen in 6 months postoperative follow up.
