Overview

Case report shows dapsone's effectiveness in reducing EAE symptoms, indicating TARC as a potential biomarker.

Key Points

  • This report aims to explore the treatment of eosinophilic annular erythema with dapsone and its effect on serum TARC levels.
  • Case report of a 50-year-old woman with eosinophilic annular erythema and elevated TARC levels
  • Treatment initiated with systemic corticosteroids and dapsone
  • Monitor serum TARC levels and cutaneous lesions during treatment.
  • Initial TARC level was 1959 pg/mL, which increased to 17310 pg/mL after corticosteroid therapy
  • Addition of dapsone led to rapid resolution of lesions and decreased TARC levels
  • Indicates potential role of TARC as a biomarker for disease activity in EAE.
