title: Tuberculous skeletal muscle involvement in acute leukemia: report on two cases.
abstract: Bacterial infection of skeletal muscle (pyomyositis) is usually followed by abscess formation. The most commonly isolated pathogen is Staphylococcus aureus. Tuberculosis rarely affects patients with acute leukemia. The authors report on 2 patients, one with acute myelogenous leukemia and the other with acute lymphoblastic leukemia whose clinical course was complicated by tuberculous skeletal muscle abscesses. In both instances, musculoskeletal pain was accompanied by evidence of muscle abscesses by imaging studies of the painful areas. Therefore, in patients with acute leukemia and evidence of muscle abscesses with initial cultures negative for bacteria and fungi, one should include tuberculosis in the differential diagnosis.
