Ameloblastoma, NOS
Nasal cavity and Sinuses


The most common odontogenic tumor, arising from the epithelial component of the embryonic tooth and usually affecting the molar-ramus region of the mandible or maxilla. Although most ameloblastomas are morphologically and clinically benign, they may cause extensive local destruction, recur, or metastasize.
