title: Cyclic neutropenia and pyomyositis: a rare cause of overwhelming sepsis.
abstract: Primary pyomyositis is a pyogenic infection of skeletal muscle with abscess formation, which traditionally lacks an identifiable cause. We present a case of pyomyositis for which a cause was established. This was largely due to the fact that the patient was young and fit, enabling him to survive such overwhelming sepsis long enough for cycling of his neutrophil count to become apparent. Having had multiple abscesses drained, he was successfully treated with granulocyte colony stimulating factor and has remained well since.
