[Angiosarcoma of the breast: mammographic and thermographic study of 4 cases].

At Istituto Nazionale Tumori of Milan four patients with histologically proven angiosarcoma of the breast were evaluated by mammography and telethermography. This is a highly malignant rare tumor which occurs more frequently in young women. The authors outline that only 90 cases have been reported in the literature (once radiologically described in 1966) and analyze clinical and especially mammographic and thermographic signs. Radiological findings simulate those of filloiden tumors or giant fibroadenomas while thermographic patterns show a nearly generalized high hyperthermia. Therefore both methods should be associated for early diagnosis and improvement of the prognosis.
