Core Tip

Core Tip: In patients with myelodysplastic syndrome, bone marrow cellularity and myeloblasts usually increase with disease progression. An advanced myelodysplastic syndrome patient experienced an episode of aplastic crisis. During the aplastic crisis, leukemic cells regressed. The bone marrow was infiltrated with atypical lymphocytes that expressed high frequencies of cluster of differentiation (CD)3, CD5, CD8, CD16, CD56 and CD57. Antituberculosis treatment led to reversion of the aplastic crisis, disappearance of the atypical lymphocytes, increased marrow cellularity and 2 mo of hematological remission, suggesting that disseminated tuberculosis was responsible for the development of aplastic crisis, regression of leukemic cells and activation of CD56+ cells.
