Migratory polyarthritis in aleukemic lymphoblastic leukemia: An undesignated paraneoplastic syndrome

Abstract

Arthritic presentation of childhood acute leukemias is well known. A subset of these children may have peripheral blast cells undetectable (aleukemic leukemia). We report classical asymmetric, fleeting type of polyarthritis involving the large weight-bearing joints along with remittent fever and normal leukocyte counts as a presenting feature of acute lymphoblastic aleukemic leukemia, deliberated as a 'paraneoplastic syndrome' of childhood.
