Vascular neoplasms of the breast

Vascular neoplasms of the breast are uncommon and can be challenging to diagnose, particularly in needle biopsies in which it can be difficult to appreciate architectural features. Here, we survey vascular neoplasms of the breast, including perilobular haemangioma, angiolipoma, capillary haemangioma, venous haemangioma, cavernous haemangioma, sinusoidal haemangioma, angiomatosis, atypical post-radiation vascular proliferation, radiation-associated angiosarcoma, and primary mammary angiosarcoma. We emphasise and illustrate key morphologic features, as well as diagnostic pitfalls and recent updates in our understanding of the molecular genetics of these tumour types.
