简介
We describe a novel gene fusion, EWSR1-CREM, identified in 3 cases of clear cell carcinoma (CCC) using anchored multiplex polymerase chain reaction, a next-generation sequencing–based technique. CCC is a low-grade salivary tumor recently characterized to have EWSR1-ATF1 fusions in the majority of cases. Three cases of malignant tumor presenting in the base of tongue, lung, and nasopharynx were studied. All cases shared a clear cell morphology with hyalinized stroma, presence of mucin and p63 positivity and were initially diagnosed as mucoepidermoid carcinoma but were negative for evidence of any of the expected gene fusions. Anchored multiplex polymerase chain reaction demonstrated a EWSR1-CREM fusion in all 3 cases to confirm a diagnosis of CCC. This finding is biologically justified as CREM and ATF1 both belong to the CREB family of transcription factors. EWSR1-CREM fusions have …
