A case report of infection of Mycobacterium senegalense after abdominal liposuction / 中国热带医学

ABSTRACT

@#Abstract Mycobacterium senegalense is one of the major pathogens causing bovine farcy, and reports of its infection in human are rare. Here is a report on a woman who had been taking hormones and immunosuppressants for a long time for SLE and underwent abdominal soft tissue infection with Mycobacterium senegalense after abdominal liposuction, to provide reference for clinical diagnosis and treatment. The patient, female, 32 years old, has a history of SLE for more than 2 years, and currently takes "methylprednisolone, hydroxychloroquine, and mycophenolate mofetil" regularly. Nine months before the patient was admitted to the hospital, she once performed abdominal, waist and buttock liposuction in a medical beauty institution. One month after the operation, several masses gradually appeared on the abdominal wall, accompanied by tenderness, one of the masses had obvious fluctuation on palpation and purulent fluid could be drawn out. The location of the abdominal wall mass was consistent with the insertion site of the liposuction needle. After the onset of the disease, the patient went to the medical beauty institution for puncture of the abdominal wall mass, and 5 mL of purulent fluid was pierced and sent for bacterial culture, and cultured "Mycobacterium Senegalense", after 3 days of treatment with "cephalosporin" antibiotics (specifically unknown), the symptoms did not improve, so she went to the second affiliated hospital of hainan medical college. After completing the relevant examinations during the hospitalization in our hospital, in order to clarify the etiology, another abdominal puncture to extract pus was performed, the mycobacterial culture + identification results: Mycobacterium senegalense. Consistent with the out-of-hospital results, the diagnosis of Mycobacterium senegalense infection was confirmed. After 3 months of treatment with "cefoxitin, azithromycin, amikacin, and levofloxacin", the patient's abdominal wall soft tissue infection was cured. Trauma or invasive procedures can lead to skin, muscle, or bone infection with nontuberculous mycobacteria (NTM), which can manifest as chronic painless nodules that progress to purulent folliculitis and abscesses. NTM infection should be suspected when the patient's wound has been exposed to water, there is a history of surgery, and empirical anti-infection is ineffective. This is the first case of Mycobacterium senegalense infection caused by medical beauty, which tell people that they should be cautious when choosing medical aesthetic projects and medical aesthetic institutions.
