Systemic loxoscelism in the age of community-acquired methicillin-resistant Staphylococcus aureus.
The increase in cases of community-acquired methicillin-resistant Staphylococcus aureus (MRSA), as well as its isolation from the majority of skin and soft tissue abscesses in the emergency department, requires the emergency physician to consider this diagnosis in all skin or soft tissue infections. However, making the diagnosis of MRSA when the wound is actually a cutaneous lesion of a brown recluse spider bite may have untoward consequences. Furthermore, the clinical manifestations of systemic loxoscelism may be misdiagnosed as a systemic staphylococcal infection. We present a patient with systemic loxoscelism who was diagnosed with a systemic infection and received an unnecessary surgical procedure.
