title: Absence of Kaposi's sarcoma-associated herpesvirus-like DNA sequences in malignant vascular tumors of the serous membranes.
abstract: Reports connect Kaposi's sarcoma-associated herpesvirus (KSHV) with various types of Kaposi's sarcoma (KS) and body-cavity-based lymphomas (primary effusion lymphomas). KSHV DNA sequences have also been detected in a few non-KS malignant vascular tumors. To determine whether KSHV is associated with malignant vascular tumors involving the body cavities, 11 primary vascular tumors of the serous membranes (4 angiosarcomas, 7 hemangioendotheliomas) were tested for KSHV sequences by polymerase chain reaction and Southern blot hybridization. The tumors were from patients who were not known to be immunocompromised. KSHV sequences were detected in the penile KS control but were absent in all 11 specimens studied. Our results were consistent with previous reports that KSHV sequences were rarely detected in non-KS vascular lesions. The results also suggested that although KSHV sequences might be present in primary effusion tumors such as primary effusion lymphoma, they might not be found in other tumors related to body cavities or to serous membranes.
