A case of angiosarcoma of the breast is described. This is an unusual, malignant, vascular tumour observed in young, fertile women. Its aetiopathogenesis, histological picture and pathological anatomy are described, and reference is made to the deceptively benign nature it often displays initially, its diagnosis, and its clinical picture. Emphasis is also placed on the limited possibilities of treatment, and its dependence on the earliest possible diagnosis for a certain degree of validity.
