Translocation (2;8)(q35;q13): a recurrent abnormality in congenital embryonal rhabdomyosarcoma.

We report a case of congenital embryonal rhabdomyosarcoma (ERMS), a rare form of rhabdomyosarcoma, featuring a karyotype with a t(2;8)(q35;q13) in a 2-week-old male infant. This is the third reported case of congenital ERMS with cytogenetic findings. The previous cases also showed a similar or possibly identical translocation. We postulate that the t(2;8)(q35;q13) is a specific abnormality in congenital ERMS, and that it involves the PAX3 gene at 2q35 and a non-yet identified gene at 8q13.
