How can the mere presence of an antibody in serum predict a tumor when it is only microscopic? This is possible in patients with certain paraneoplastic neurologic syndromes (PNS) as shown by Mathew et al.1 in this issue of Neurology . Since the first description of antineuronal antibodies (anti-Hu) in 1984 by Posner et al., the association of a neurologic syndrome, an antineuronal antibody, and a microscopic or relatively biologically benign tumor have frequently been recognized.2 Mathew et al. describe six patients with anti-Ma2/Ta antibody whose clinical findings predicted a testicular tumor even though diagnostic tests had been negative. In the face of clinical progression, orchiectomy was performed and a microscopic tumor was identified.1 This article highlights several important clinical points. Anti-Ma2/Ta is indeed a highly specific marker for the presence …
