[Bone marrow biopsy in the diagnosis of hematopoietic tuberculosis].

The authors report 6 cases of tuberculosis of the bone marrow, in which the diagnosis was made by biopsy. Three of these cases, included peripheral blood abnormalities, such as pancytopenia, whereas in the three other, nothing special was found on routine blood examination. All the patients, except one who died from intercurrent infection, became cured thanks to anti-tuberculosis treatment. Marrow biopsy thus permits early diagnosis, miliary tuberculosis, even when usual radiological and bacteriological investigations are negative.
