Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) infections are prevalent among children, students, and families. CA-MRSA infections often cause skin and soft tissue infections (SSTIs); however, there are few reports of lymphadenitis, which is typically mono-lymphadenitis [1]. Furthermore, the sequence type (ST) 834 strain, as determined by multilocus sequence typing analysis, has rarely been reported, and its epidemiological characteristics and pathogenicity remain obscure. A limited number of reports have documented ST834 MRSA infections, primarily in Asia. This strain is characterized by the presence of pathogenicity islands known as SaPIsaitama2, which contain the toxic shock syndrome toxin 1 gene (tst) [[2], [3], [4], [5], [6]]. Here, we report a case of unilateral multifocal lymphadenitis caused by ST834 CA-MRSA.
