It accounts for only 4% to 13% of all ameloblastomas. Desmoplastic ameloblastoma (DA) was included in the World Health Organization Classification of Head and Neck Tumors (WHO-2005) as a variant of ameloblastoma with specific clinical, imaging and histological features. The desmoplastic variant of ameloblastoma usually appears in the anterior and premolar regions as a mixed radiolucent and radiopaque lesion, sometimes resembling a benign fibro-osseous lesion [1]. Ameloblastoma is a locally aggressive tumor that may cause recurrence and in rare cases, malignant transformation with repeated postsurgical recurrences [2] [3]. In this paper we present a case of a 47-year-old female with swelling in the left upper jaw, bopsy of which turned out to be desmoplastic ameloblastoma.展开更多

They most often occur in the mandibular ramus. We present a case of “hybrid” lesion—desmoplastic and conventional ameloblastoma—in the anterior mandible, focusing on its’ imaging features.展开更多
