Fine-needle aspiration of renal angiosarcoma.
Angiosarcoma of the kidney is an unusual neoplasm, and primary renal angiosarcoma is exceedingly rare, with fewer than 11 well-documented cases reported to date. To our knowledge, no publication to date has correlated the fine-needle aspiration cytologic findings in renal angiosarcoma with the gross, histologic, and immunohistochemical findings. A 50-year-old man presented with a left kidney mass and multiple liver and pulmonary nodules. Computed tomography-guided fine-needle aspiration biopsies of the renal mass and a hepatic nodule were performed and demonstrated malignant spindle cells consistent with angiosarcoma. The diagnosis was confirmed at autopsy through histologic examination and associated ancillary studies. This case presents the fine-needle aspiration cytologic findings in renal angiosarcoma and correlates these findings with the gross pathologic, histologic, and immunohistochemical findings.
