8) Coamplification of the FMS-like tyrosine kinase 4 (FLT4) gene encoding the vascular endothelial growth factor receptor 3 (VEGFR3), in association with MYC amplification, was found by Guo et al (10) in 25% of secondary angiosarcomas but not in other radiation-associated, atypical vascular lesions.
Immunohistochemical staining and fluorescence in situ hybridization for MYC are helpful in distinguishing benign and atypical vascular lesions (AVLs) from secondary angiosarcoma because expression and amplification of MYC have been described in secondary angiosarcomas and are absent in AVLs.
