Alveolar rhabdomyosarcoma (ARMS)

Available test Fluorescence in situ hybridisation analysis for FKHR (FOXO1A) t(13q14;)
Clinical details: 
Alveolar rhabdomyosarcoma (ARMS) can generally be distinguished from other round cell tumours by histology and immunohistochemistry, but approximately 80% of ARMS cases rearrangement of FKHR (FOXO1A) and the detection of such abnormalities by FISH can be important in confirming the diagnosis and distinguishing ARMS from embryonal rhabdomyosarcoma, which does not show FKHR rearrangement.
