"Hybrid" lesion of desmoplastic and conventional ameloblastoma: immunohistochemical aspects.
Ameloblastoma is a benign epithelial odontogenic tumor and is the most commonly encountered odontogenic tumor in the jaws. Histologically, ameloblastomas occur in different patterns, including plexiform pattern and follicular pattern. "Hybrid" lesion of ameloblastoma is a tumor variant in which histologically, areas of follicular or plexiform ameloblastoma coexist with characteristic areas of a...

متن کاملPeripheral Desmoplastic Ameloblastoma in Adolescent Age: Clinico-Pathological and Immunohistochemical Analisys of a Case
The Extraosseous or Peripheral Ameloblastoma (PA) is a rare and benign odontogenic tumour, representing 1% to 5% of all ameloblastomas. It is usually localized in the soft oral tissues, without deep bone involvement. Its biological behaviour is specific, and several authors define PA as a non-infiltrating hamartomatous lesion. Indeed, recurrences rarely occur and progression in malignant tumors...
