Figure 2: Histologic features of Kaposi’s sarcoma in the nodular stage (hematoxyline-eosin stain). A. The dermis is expanded by a solid tumor nodule (original magnification 40X). B. Fascicles of relatively monomorphic spindled cells, with slit-like vascular channels containing erythrocytes (original magnification 400X). C. The nuclei of the tumor cells (yellow arrow) demonstrate immunoreactivity for HHV-8 (LNA-1 immunohistochemical stain).
