Atypical vascular lesions (AVLs) are vascular proliferations that develop after surgery and radiation for breast carcinoma and may represent precursors to angiosarcoma.


A vascular papule or nodule on the breast is typical. Lesions in the axilla may be seen. The latency period for development of these lesions ranges from 1 to 20 years after radiation, although presentation within 3 to 6 years is most common.
