Ameloblastoma relapse after 50 years from resection treatment

Ameloblastoma is a slow-growing, locally invasive, epithelial odontogenic tumor of the jaws with a high rate of recurrence if not removed adequately but with virtually no tendency to metastasize (World Health Organization Classification of Tumors: Pathology and Genetics of Head and Neck Tumours, 2005). This paper presents a case of a woman who was treated in 1961, when she was 25 years old, for an ameloblastoma in the right posterior region of the mandible. After 50 years, the ameloblastoma relapsed, and another surgical treatment was necessary.
