Histological findings in blood-borne brain lesion. A. The multiple hemorrhagic nodules showed whorls of spindle-shaped cells and neovascularization with small-vessel proliferation characteristic of Kaposi’s sarcoma (hematoxylin-eosin stain; original magnification, ×400). B. Tumour cells invaded brain parenchyma through perivascular space (hematoxylin-eosin stain; original magnification, ×200). C. Neoplastic nodules showed hemorrhagic necrosis with pigmented macrophages (hematoxylin-eosin stain; original magnification, ×200). D. The neoplastic cells show strong cytoplasmic staining for CD34 (immunoperoxidase on a paraffin embedded section, original magnification, ×400).
