Methicillin-Sensitive Staphylococcus aureus-Associated Leukocytoclastic Vasculitis: A Case Report and Literature Review
Abstract
The association of Staphylococcus aureus with vasculitis remains relatively rare and poorly understood. In this report, we present a case of Methicillin-sensitive Staphylococcus aureus (MSSA)-associated leukocytoclastic vasculitis (LCV) following a surgical site infection, adding to the limited body of knowledge on this intriguing clinical entity. A 52-year-old male with a medical history significant for type 2 diabetes mellitus, hypertension, hyperlipidemia, and coronary artery disease presented with progressively worsening generalized petechial rash and migratory joint pains with associated joint swelling. The patient's symptoms began following surgical repair for a rectus abdominis incisional hernia with mesh placement that was complicated by an abdominal wall abscess at the surgical site, prompting drain placement. Cultures from the abscess aspirate revealed Methicillin-sensitive Staphylococcus aureus infection. A punch biopsy of the petechial lesions revealed findings consistent with leukocytoclastic vasculitis. The rash and joint pains resolved approximately one week after initiation of treatment with antibiotics and steroids. This case sheds light on the rare but clinically significant association between Methicillin-sensitive Staphylococcus aureus infection and leukocytoclastic vasculitis, particularly following surgical site infections. The prompt recognition and treatment of underlying MSSA infection, along with the targeted management of LCV, resulted in the…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
