[Radiologic features of desmoplastic ameloblastoma].
OBJECTIVE
To investigate the radiologic features of desmoplastic ameloblastoma.


METHODS
The radiologic characteristics of 15 cases desmoplastic ameloblastoma which were diagnosed pathologically were analyzed retrospectively, and compared with solid or multicystic ameloblastoma.


RESULTS
Desmoplastic ameloblastoma were mainly located in anterior and (or) premolar region of maxilla and mandible. There existed three features radiologically. 1. unilocular formation containing varying amounts of radiopaque islands or strands material. 2. multilocular destruction containing irregular or line-like radiopaque areas. 3. mixed destruction showing plxiform radiopaque material and unilocular change. Typical microscopic features were irregular and compressed epithelial islands or strands interspersed among dense fibrous connective tissue stroma.


CONCLUSIONS
The desmopleatic ameloblastoma is a new type of ameloblastoma and exhibits some special characteristics radiologically and pathologically. It should be differentiated from osteofibroma and odontogenic myxoma.
