Anetoderma before development of antiphospholipid antibodies: delayed development and monitoring of antiphospholipid antibodies in an SLE patient presenting with anetoderma


Introduction: Anetoderma is an elastolytic skindisorder that has been associated with the presenceof antiphospholipid antibodies (aPL). Patients withantiphospholipid antibody-positive anetoderma havebeen reported to develop symptoms of Graves disease,antiphospholipid syndrome, and other autoimmuneconditions. The temporal relationship, however,between anetoderma onset and the emergence ofaPL remains unclear, a clarification of which may haveimplications for the screening and monitoring ofpatients with anetoderma. Case: Herein we report acase of a patient with systemic lupus erythematosuspresenting with anetoderma that preceded thedevelopment of aPL. The patient was found to havesubsequently developed IgM cardiolipin antibodiesat a serology follow-up approximately two years later.Conclusion and Relevance: This finding suggests thatanetoderma can precede aPL seroconversion andthat patients with anetoderma may require continuedserology monitoring. Such long-term monitoring willbe important for identifying laboratory indicationsthat may portend the development of furtherautoimmune symptoms associated with anetoderma.
