It is a rapidly growing non-odontogenic neoplasm of the jaws, generally occurring in children and young adults. It is often confused with malignant condition because of its clinical behaviour. Long term follow-up is necessary, considering the high recurrence nature of this tumour. The reconstruction of affected patients, particularly the younger, is often challenging since it has to be done in stages, to keep up with the developing face. We report a case of maxillary JAOF in a 6-month-old female who was referred to our department. Histopathological examination of a resected specimen revealed a trabecular type of JAOF. The patient was followed up for a period of 2 years.展开更多

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
