Kaposi's Sarcoma-Associated Herpesvirus-Related Solid Lymphoma Involving the Heart and Brain
Figure 2
(a) Cerebrospinal fluid contains rare large, atypical cells with lobated nuclei and abundant basophilic cytoplasm; scattered smaller nonneoplastic cells are also present. (b)–(d) Endomyocardial biopsy. Microscopic examination by hematoxylin and eosin stain shows an atypical lymphoid proliferation infiltrating the myocardium (b). Higher power revealed large atypical discohesive cells with few admixed eosinophils (c). Large lymphoid cells stained avidly for Kaposi’s sarcoma herpesvirus by immunostain (d).
