ASYMPTOMATIC PRIMARY BREAST ANGIOSARCOMA IN 45-YEARS-OLD WOMAN
P rimary breast angiosarcoma is an extremely rare tumour type (0.05% of primary breast cancers with an incidence of 4.5 cases per million in the USA), so diagnosis can be difficult. They arise within the breast parenchyma and generally present as a breast mass. This report presents the case of a 45-year-old woman who attended the imaging department to participate in the screening program of early detection of breast cancer. A core needle biopsy revealed an angiosarcoma. This case points to the subtle imaging findings in a lesion smaller than one centimeter (mammogram and ultrasound) that led the radiologist to perform a biopsy to find malignant breast cancer in a patient with no history of any known risk factors.
