(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. Based on those results, they suggest that FLT4 overexpression may represent a required second hit in the progression of secondary angiosarcomas.
In 1994, Fineberg and Rosen3 reported 4 cases of an unusual vascular lesion occurring in mammary skin after radiation, which they named atypical vascular lesion (AVL).
Atypical vascular lesion usually presents as 1 or more small, flesh-colored papules or erythematous patches that arise in radiated skin.
