Left thigh phlegmon caused by Nocardia farcinica identified by 16S rRNA sequencing in a patient with Leprosy: a case report

Background In recent years, Nocardia farcinica has been reported to be an increasingly frequent cause of localized and disseminated infections in the immunocompromised patient. However, recent literature is limited. We report a case of left thigh phlegmon caused by N. farcinica that occurred in a patient with Leprosy undergoing treatment with prednisone for leprosy reaction.
