Abstract

The Nocardia species are aerobic Gram-positive filamentous bacteria found worldwide in soil and decaying organic plant matter. Primary cutaneous nocardiosis is a rare entity and most commonly caused by Nocardia brasiliensis (N. brasiliensis). However, it can rarely be caused by N. farcinica, which is recognized as a human pathogen. Here we report a case of a 54-year-old female patient who presented with erythematous nodules on her abdomen for 1 week. She had been treated with methotrexate and prednisolone due to systemic lupus erythematosus and rheumatoid arthritis. By bacterial culture and 16S ribosomal RNA gene sequencing, the patient was diagnosed with a primary cutaneous nocardiosis caused by N. farcinica, which has not previously been reported in the Korean dermatological literature.
