Popis: Background The rare occurrence of angiosarcoma of the breast is reflected in limited descriptions of fine needle aspiration (FNA) cytomorphologic findings in this neoplasm. We present a case of angiosarcoma of the breast and discuss the pitfalls in diagnostic cytopathology that can potentially lead to incorrect diagnoses in such cases. Case A 45-year-old woman presented with a 2-year history of a right-sided breast mass. FNA cytology revealed a hypocellular smear composed of cohesive ductal epithelial cells; isolated or loosely arranged, round in spindle-shaped fibroblastlike cells; and projectile growths of round, oval and polygonal cells ou loose tangles of connective tissue. The background was hemorrhagic, with scattered foam cells. The overall cytologic diagnosis was inconclusive but suggested phyllodes tumor (of borderline malignancy). Excisional biopsy was performed, followed by smimple mastectomy. Histologic features were consistent with angiosarcoma, a
