PITFALLS IN THE CYTOLOGIC DIAGNOSIS OF ANGIOSARCOMA OF THE BREAST BY FINE-NEEDLE ASPIRATION - A CASE-REPORT

This paper describes a case of angiosarcoma of the breast in a 26-yr-o ld female. The tumor, originally thought to be granulation tissue on f ine-needle aspiration biopsy, was correctly identified as a malignant neoplasm of probable mesenchymal origin on a repeat FNA biopsy 4 mo la ter. A diagnosis of angiosarcoma was made on a subsequent excisional b iopsy. Review of the cytologic features revealed findings that should suggest angiosarcoma, especially when correlated with the clinical his tory. The authors describe the cytological features seen in this case, and discuss an important pitfall in the diagnosis of angiosarcoma of the breast on FNA. (C) 1994 Wiley-Liss, Inc.
