[Clinicopathological analysis of 15 cases of desmoplastic ameloblastoma]

15 cases of desmoplastic ameloblastoma (DA) were studied clinicopathologically, which was combined with literature review of 50 cases. The results showed that the morbidity of DA was low, which occupied 7.4% of the whole ameloblastoma. The DA tumor occurred preferentially in anterior parts of the jaw and the maxillary bone, which exhibited radiographically a mixed radiolucent-radiopaque appearance, and the main pathological characteristic was extensive fibrous hyperplasia in stroma and scattering epithelial nests with different sizes. Some cases showed a mixture type of DA and classical ameloblastoma.
