ABSTRACT
BACKGROUND:
In December 2023, our hospital confirmed a case of systemic lupus erythematosus complicated with Mycobacterium leprae infection. The patient has extensive patchy erythema on the back and face, with obvious itching. There are multiple subcutaneous masses on both hands, some of which are accompanied by tenderness, wave sensation, and other symptoms. The patient's mother has a history of leprosy and close contact with the patient. The patient tested positive for syphilis antibodies 2 years ago and did not receive formal treatment. There is no other history of chronic illness.METHODS:
Under local anesthesia, the left hand skin lesion was excised, followed by tissue pathological biopsy, acid-fast staining, mNGS, and serum Treponema pallidum antibody detection.RESULTS:
Pathological biopsyresults:
A large number of foam-like histiocytes, lymphocytes, and plasma cells were mainly found in the superficial and deep layers of the dermis, as well as around the blood vessels and sweat glands in the subcutaneous fat. Cellulose-like degeneration is seen in some blood vessel walls. Tissue acid-fast staining positive, tissue mNGS detection Mycobacterium leprae. CLINICAL DIAGNOSIS 1. Borderline leprosy, 2. Subacute cutaneous lupus erythematosus. Treat with methylprednisolone 32 mg qd po + aluminum magnesium suspension 15 mL tid po + calcium carbonate D3 tablets 0.6 g qd po + rifampicin 450 mg qd po + dapsone 100 mg qd. After 10 days of treatment, the patient improved and was discharged from the hospital.CONCLUSIONS:
Mycobacterium leprae infection occurs during SLE treatment and is often difficult to distinguish from skin symptoms caused by SLE. In the clinical treatment of infectious diseases, the effect of conventional anti-bacterial drugs is not good. The auxiliary examination indicates severe infection and the routine culture is negative. The possibility of special pathogen infection should be considered in combination with the medical history. With the popularity of new detection methods such as mNGS, the importance of traditional smear detection methods cannot be ignored.
