Nannizziopsis spp., fungi responsible for emerging diseases, are rarely involved in human bone and joint infections. We present a rare case of septic arthritis with necrotizing cellulitis caused by N. obscura in a patient in France who had undergone kidney transplant. Rapid, aggressive medical and surgical management led to a favorable outcome.
