An Acute Nocardia Infection in a Pediatric Hand.

Nocardia species are aerobic gram-positive filamentous organisms that may cause cutaneous or pulmonary disease in humans. Primary cutaneous nocardiosis may manifest as an acute superficial pyogenic infection that can mimic more common organisms such as Staphylococcus or Streptococcus. Acute pyogenic Nocardia infection of the pediatric hand is a rare manifestation of this condition. We present a 17-month-old boy who presented with an acute abscess formation on his left fourth and fifth digits that was found to be secondary to Nocardia brasiliensis.
