Leukaemoid reaction and disseminated tuberculosis. A case report.

Four cases of leukaemoid reactions to tuberculosis, notwithstanding the presence of Auer's rods in the myeloblasts, have previously been reported. A fifth case of disseminated tuberculosis in which Auer's rods were similarly observed, is described. However, we believe that this association does not mean that Auer's rods occur as part of a leukaemoid response, but rather that it indicates the simultaneous presence of acute leukaemia and tuberculosis.
