Testicular nocardiosis accompanied by cutaneous lesions in an immunocompetent man.

We herein report the case of a 77-year-old man admitted for an acute cutaneous infection and persistent fever. A physical examination revealed systemic small blisters and scrotal swelling. He was suspected of having complications from chickenpox or bullous impetigo as the initial diagnosis. Nocardia was detected on an aspiration biopsy of the small blisters and the surgically removed testis at a later date. Testicular nocardiosis is a rare condition; however, we should consider nocardiosis in the differential diagnosis because delay in providing treatment may worsen a patient's general condition.
