Tuberculosis, caused by Mycobacterium tuberculosis is a common infection both in immunocompromised and normal hosts. Its clinical manifestation can by divided as pulmonary and extrapulmonary form. Pyomyositis caused by M. tuberculosis is extremely rare. The authors report 2 patients, one with underlying dermatomyositis, and the other with polymyositis. The diagnosis was delayed according to nonspecific symptoms and masking effect of steroid therapy, which led to complications. Microscopy and culture of the pus confirmed the diagnosis. Surgical drainage was done and antituberculous therapy was given. The patient with dermatomyositis was complicated by drug induced hepatitis and died but the other was cured. Tuberculous pyomyositis should be considered in patients who are immunocompromised hosts.
