title: [Benign metastatic ameloblastoma. A case report and review of the literature].
abstract: A 78 year old woman with a history of maxillary ameloblastoma from age of 38 years was found on routine examination to have a pulmonary image of the balloon release type. The lesion was atypical with respect to its clinical tolerance and slow progression. Pathology of several nodules removed by surgical lung biopsy confirmed the benign nature and identity of the maxillary and pulmonary lesions. The diagnosis was therefore pulmonary metastases from a benign ameloblastoma. The age of the patient and slow course of the lesion, combined with the absence of any functional disorder, was the basis for the decision not to operate on the pulmonary lesion. The concept of benign metastatic ameloblastoma is analyzed and findings compared with data in the literature.
