Vascular-type lesions may warrant closer post-radiation surveillance; hypothesis-generating and requires prospective validation before practice change.
Observational (n=32)
Atypical vascular lesions after breast radiation encompass a spectrum of lymphatic and capillary lesions and may serve as precursors to angiosarcoma, particularly those with vascular type histology or endothelial atypia.
Patton et al. (2008) conducted an observational in Atypical vascular lesions after surgery and radiation of the breast (n=32). Atypical vascular lesions (lymphatic and vascular types) was evaluated on Clinical outcomes including recurrence and progression to angiosarcoma. Atypical vascular lesions after breast radiation encompass lymphatic and vascular types, with the vascular type carrying a higher risk of progression to angiosarcoma.
