EWSR1 and ATF1 rearrangements in clear cell odontogenic carcinoma: presentation of a case.

Abstract

Clear cell odontogenic carcinoma (CCOC) is a rare odontogenic tumor of the jaws that is more common in the mandible than maxilla and has a female preponderance with a peak incidence in the sixth decade. It is characterized by locally aggressive behavior and has the potential to metastasize. This tumor was recently reported to have a rearrangement of the Ewing sarcoma breakpoint region 1 gene (EWS RNA-binding protein 1, EWSR1) in 5 of 8 cases tested and of the activating transcription factor 1 gene (ATF1) in 1 case tested. We report a case of CCOC in the premolar area of the mandible in a 59-year-old woman. This case demonstrated the presence of both EWSR1 and ATF1 gene rearrangements by fluorescence in situ hybridization.
