title: Persistent lymphadenopathy in homosexual men: a clinical and ultrastructural study.
abstract: Ultrastructural changes (tubuloreticular structures and tube and ring shaped forms) previously described in patients with acquired immunodeficiency syndrome (AIDS) are described for the first time in the lymph nodes and circulating lymphocytes of patients with persistent lymphadenopathy. These observations support the view that the persistent lymphadenopathy syndrome and AIDS are caused by the same transmissible agent(s).
