title: Secondary polycythemia associated with multiple myeloma.
abstract: A 58-year-old man with polycythemia of more than 8 years duration developed multiple myeloma. Extensive examination indicated his polycythemia to be of a secondary type, but failed to reveal an underlying disorder. To the best of our knowledge, this is the first reported association of multiple myeloma in a patient with definitely-diagnosed secondary polycythemia.
