Abstract Human adenoviruses possess oncogenic capacity which is well documented in mammalian animal models, but their possible implication in human malignancy has remained enigmatic. Following primary infection, adenoviruses can persist in a latent state in lymphocytes where the virus is apparently able to evade immune surveillance. In the present study, we have employed a broad-spectrum adenovirus polymerase chain reaction (PCR) assay to systematically screen more than 200 diagnostic specimens of different lymphoid malignancies including acute lymphocytic leukaemia ( n = 50), chronic lymphocytic leukaemia ( n = 50), various types of malignant lymphoma ( n = 100) and multiple myeloma ( n = 11) for the presence of adenoviral sequences. While most entities analysed revealed negative findings in virtually all specimens tested, adenoviral DNA was detected in 15/36 (42%) mantle cell lymphomas investigated. The most prevalent adenoviral species detected was C, and less commonly B. Adenovirus-positive findings in patients with mantle cell lymphoma were made at different sites including bone marrow ( n = 7), intestine ( n = 5), lymph nodes ( n = 2) and tonsillar tissue ( n = 1). The presence of adenoviral sequences identified by PCR was confirmed in individual cells by fluorescence in-situ hybridisation (FISH). The frequent observation of adenoviruses in mantle cell lymphoma is intriguings, and raises questions about their possible involvement in the pathogenesis of this lymphoid malignancy.
