[online]. 2006, vol.46, n.6, pp. 424-427. ISSN 1809-4570. http://dx.doi.org/10.1590/S0482-50042006000600012.
Sometimes, it is not possible to establish an obvious distinction between the muscular manifestations due to infectious diseases and the idiopathic myositis. In fact, in some situations it is believed there is a causal relationship between those diseases. We describe the case of a patient with clinical and laboratorial features of polymyositis who had developed leptospirosis previously. The hypothesis of the infectious agent acting as a "trigger" to the muscular disease is discussed.
