An inflammatory disease caused by the spirochete Borrelia burgdorferi that manifests itself in the skin as erythematous lesions with figurate shapes, e.g., (round, ellipsoid, and arcuate) (erythema chronicum migrans), pseudolymphomatous nodules (lymphadenosis benigna cutis), and acral patches and plaques that in time become atrophic (acrodermatitis chronica atrophicans).
