Through the reports of the literature, the histopathologic lesions of the bone marrow in tuberculosis of the hematopoietic organs are analysed. Whether the lesions are typical or not, it is necessary to have a bacteriologic proof of tuberculosis. Near these lesions, bone marrow's cellularity is often greater or lower, reticular fibers are often increased and sometimes reticulin fibrosis is marked. Other necrosis and granulomatous inflammation are discussed. Contribution of macrophage is described. The relationships between tuberculosis and hematologic diseases are reported.
