Angiosarcoma of the breast is an aggressive malignancy of endothelial origin with a tendency for localregional recurrence. The involvement of angiosarcomas in the bilateral breasts has rarely been documented. Of note, due to its rarity and typically unclear clinical findings upon examination, the diagnosis of a contralateral lesion can be difficult, particularly in women during pregnancy. Here we present a rare case of bilateral angiosarcoma of the breast during pregnancy. A 32-year-old woman was referred to our unit with complaints of progressive swelling of the left breast, with tenderness. Magnetic resonance imaging showed a small, circumscribed high-intensity area in the contralateral breast, with pattern similar to that of the lesion found in the left breast. The contralateral lesion revealed only equivocal findings with the other diagnostic modalities. Diagnosed as angiosarcoma preoperatively, excision of the bilateral tumors was performed. Histological findings of the removed bilateral tumors were compatible with high-grade angiosarcoma of the breast.
