Angiosarcoma primario de mama bilateral sincrónico en el periodo de lactancia

Primary angiosarcoma of the breast is an uncommon aggressive tumour. Its diagnosis is particularly difficult because it occurs in young women and the clinical and imaging findings are non-specific and may simulate inflammatory or infectious entities. This tumour has been associated with pregnancy, although it has not been shown to be a hormone-dependent tumour. We present a case of bilateral synchronous angiosarcoma of the breast with onset in the lactation period. Despite being an extremely rare neoplasm, it should be included in the differential diagnosis of a rapidly growing palpable lesion in young women.
