Sterile subconjunctival abscess in an HLA-B51-positive patient with ulcerative colitis

Abstract

Purpose: To report a rare case of aseptic abscess presenting as a subconjunctival abscess in an HLA-B51-positive patient with ulcerative colitis. Observations: A 25-year-old, male, Japanese patient with ulcerative colitis presented with an unilateral subconjunctival abscess. Infective endocarditis with endophthalmitis was suspected of being the cause, and systemic antimicrobial therapy was begun. The patient became critically ill and experienced the complication of heart failure with mitral valve perforation but improved dramatically with high-dose corticosteroids and intravenous infliximab following mitral valvuloplasty. His HLA typing was positive for HLA-B51. Conclusions and importance: Both infectious and non-infectious etiologies should be considered in a patient with a subconjunctival abscess with systemic inflammation. An aseptic abscess can present as a subconjunctival abscess, and HLA-B51 may play a role in the pathogenesis of this rare condition.
