Nocardiosis is a rare serious infectious disease caused by the invasion of the human body by the genus Nocardia, which can occur in immunosuppressed hosts as well as in immunocompetent individuals. The disease is mainly caused by inhalation of Nocardia spores through the respiratory tract, broken hyphal fragments or direct infection of the skin, involving multiple tissues and organs. In clinical practice, the diagnosis of Nocardia infection is extremely challenging, and it is easy to be misdiagnosed and missed.
