A Case of Systemic Lupus Erythematosus Diagnosed from Aseptic Abscess in a Patient Who Underwent Acute Type A Aortic Dissection

We report the case of a 43-year-old man with acute type A aortic dissection. Aortic arch replacement was performed. During postoperative recovery, erythema and swelling around the midline wound was observed. As purulent discharge was observed when an incision was made, a specimen was sent for culture, but all tested negative. As the results were found to be aseptic, we performed omental implantation. The department of rheumatology was consulted. They suspected SLE, and treatment with prednisolone was initiated. The patient was discharged after an uneventful recovery. we encountered a rare case in which SLE was diagnosed from aseptic abscess.
