Myelitis Presenting Anti-Yo Antibody in a Patient with Prostatic Adenocarcinoma

Antineuronal antibody-associated paraneoplastic neurologic syndromes result from tumor-stimulated autoimmune attacks against components of the nervous system. Paraneoplastic myelopathy associated with Purkinje-cell cytoplasmic autoantibody type 1 (anti-Yo) is extremely rare disorder. It is almost exclusively reported in women with gynecological tumors. Even though few cases of anti-Yo-associated paraneoplastic neurologic syndrome related to other cancers are reported, it is a very uncommon condition, especially in males. The author report here the first case of anti-Yo myelopathy with prostatic adenocarcinoma.
