EWSR1-associated tumors

Monday 15 July 2013

Tumors (examples)

- Ewing group of tumors

  • Ewing sarcoma
  • pPNET

- clear cell odontogenic carcinoma (23715163)

  • Clear cell odontogenic carcinomas (CCOCs) are a rare tumor of the jaws, which have considerable morphologic and immunophenotypic overlap with (hyalinizing) clear cell carcinomas (CCCs) of salivary origin.
  • Some studies demonstrate the EWSR1-ATF1 translocation in a CCOC and demonstrate a concrete link between CCCs and at least a subset of CCOCs. (23715163)
