Pyomyositis mimicking leptospirosis: two cases in a Brazilian tertiary care hospital in a non-tropical area.
Pyomyositis is a subacute, deep suppurative bacterial infection of skeletal muscle not arising from contiguous infection. It is presumably haematogenous in origin, and characterized by muscle pain and swelling. We report on two patients who presented with pyomyositis in a tertiary care hospital in temperate region located in southern Brazil with a clinical presentation, which was initially suggestive of leptospirosis. This report discusses the pathogenesis, clinical presentation, diagnosis and management of pyomyositis. Physicians living in non-tropical areas should note that pyomyositis might occur in those areas, and its initial clinical presentation may be similar to leptospirosis.
