Primary Tuberculous Pyomyositis of the Left Forearm Muscles

Pyomyositis, often caused by <i>Staphylococcus aureus</i>, is a rare primary infection of skeletal muscle and is usually associated with abscess formation. Pyomyositis caused by <i>Mycobacterium tuberculosi</i>s is extremely rare. In this paper, by presenting a case of tuberculous pyomyositis, we tried to provide a simple answer to the question of when we should consider <i>M. tuberculosis</i> in the etiology of pyomyositis.
