Version 2: HIV combined with skin infection of Nocardia brasiliensis: A rare case report

Introduction. The HIV virus can attack and gradually damage the human immune system, causing the host to be unprotected when infected. Nocardia is a type of opportunistic pathogenic bacteria that can easily cause infections in patients with chronic wasting diseases, immune dysfunction, and the use of immunosuppressants. Nocardia can invade various tissues and parts of the body, causing corresponding clinical symptoms. There are few reports of HIV patients being infected with Brazilian Nocardia.

Case presentation. This article reports a case of an HIV patient with concurrent infection with Brazilian Nocardia. A patient with HIV developed a lump on the surface of their left skin without any obvious cause. Due to improper disinfection and treatment methods, the condition worsened, and they subsequently sought medical attention at our hospital. A series of laboratory related tests are conducted clinically based on the patient's medical history, symptoms, and signs. Based on the test results, a reasonable treatment plan was adopted clinically, ultimately achieving satisfactory treatment outcomes for patients.

Conclusion. HIV patients are prone to various types of infections, even rare bacteria, as their immune function decreases. With the popularity of new identification methods such as mass spectrometry, laboratories should pay attention to traditional staining methods and use microscopes to detect pathogens.
