Nocardiosis in South Texas children.

Primary cutaneous nocardiosis can present as cellulitis or abscess with or without lymphadenitis. In South Texas children with suspected Staphylococcus aureus or Streptococcus pyogenes skin and soft tissue infections who do not improve as expected with appropriate antibiotics, physicians should consider Nocardia brasiliensis in the differential diagnosis, especially if there are multiple lesions in a lymphocutaneous distribution.
