Staphylococcus aureus panniculitis complicating juvenile dermatomyositis.

Panniculitis is a rarely reported manifestation of juvenile dermatomyositis. The 3 previously reported cases of juvenile dermatomyositis and panniculitis were attributed to flare of underlying disease, rather than infection, and were treated with increased immunosuppression. Here we describe a patient with juvenile dermatomyositis who developed panniculitis secondary to Staphylococcus aureus. Patients with juvenile dermatomyositis and panniculitis should have extensive testing for infectious etiologies before increasing their immunosuppressive regimens.
