Abstract

Combined epithelial odontogenic tumor was first described by Damm in 1982 as a rare tumor characterized by the presence of calcifying epithelial odontogenic tumor (CEOT) areas in adenomatoid odontogenic tumor (AOT). Histologically, the tumor shows relatively small epithelial nests forming duct-like structures and markedly hyalinized fibrous tissue stroma containing amorphous and irregularly shaped calcified tissue and amyloid-like materials. There are several round-shaped masses that show Liesegang rings. This article describes a case of adenomatoid odontogenic tumor with calcifying epithelial odontogenic tumor-like areas, so-called combined epithelial odontogenic tumor, between the right lateral incisor and the left canine region in the mandible.<BR>A 27-year-old woman was referred to our clinic for evaluation of a mixed radiolucent-radiopaque lesion with a well-defined border in the mandible. A computed tomographic scan demonstrated a well-defined large lesion that extended widely, with thinning of the cortical bone of the mandible. The lesion was associated with an impacted canine in the mandible.<BR>Surgery was performed with the patient under general anesthesia.The tumor was enucleated completely via an intraoral approach. Wound healing is currently good, 9 months after surgery.
