Testicular tumor. A, Immunoperoxidase staining for CD34 demonstrates strong positive reactivity in malignant endothelial cells lining the vascular channels (immunoperoxidase, original magnification ×200). B, Immunoperoxidase staining for CD31 demonstrates strong positive reactivity in malignant endothelial cells lining the vascular channels (immunoperoxidase, original magnification ×200). C, Immunoperoxidase staining for Ulex Europaeus lectin demonstrates positive reactivity in malignant endothelial cells lining the vascular channels (immunoperoxidase, original magnification ×200). D, Immunoperoxidase staining for Pancytokeratin demonstrates negative reactivity in the malignant endothelial cells lining the vascular channels (immunoperoxidase, original magnification ×200).
