Sumario:A 78-year-old man with a history of surgical resection for ameloblastoma 31 years earlier visited our hospital for prolonged cough. Chest computed tomography showed multiple nodules in both lungs. Although there was no local recurrence in the mandible, the specimen taken from a transbronchoscopic bronchial biopsy showed recurrent ameloblastoma. Despite receiving no treatment, the disease in our patient remained clinically stable for 8.4 years. Chest physicians should be aware that pulmonary malignant ameloblastoma can first relapse several decades after curative surgery. In addition, pulmonary malignant ameloblastoma without local recurrence may be associated with a good prognosis.
