| A rare odontogenic neoplasm with characteristics of aggressive clinical course and local destruction, occurring in mandible more often than in maxilla. The most common symptom is a rapidly progressing painful swelling but it may present as a benign cystic lesion or as a large, rapidly growing mass with ulceration, bone resorption and teeth mobility, as well. The neoplasm may metastasize, most commonly to the cervical lymph nodes and the lungs. |
