A Case of Mycolicibacterium mucogenicum Infection in the Right Back

In November 2023, our hospital confirmed a case of Mycolicibacterium mucogenicum infection in the right back. The patient sought medical attention at our hospital due to "a right back lump for 2 months, ruptured for 1 month." Two months ago, the patient's back collided with a fire hose and developed a local walnut sized lump. The lump was soft, painless when pressed, and there was no obvious redness or swelling around it. The patient went to a private hospital for incision and drainage treatment on their own. One month later, the condition did not improve and there was yellow pus exuding from the incision site. For additional diagnosis and treatment, the patient went to our hospital for treatment.
