[Lyme disease: cutaneous involvement and treatment of the initial phases]

Lyme disease is a tick-transmitted infectious disease caused by Borrelia burgdorferi. The clinical spectrum includes manifestations in the skin, heart, joints and nervous system. In Brazil no case has been reported with laboratorial confirmation. We report a suspect case with clinical and laboratorial findings in a young woman who developed cutaneous manifestations. She recovered after tetracycline treatment. The usual manifestations and the treatment of early stage of the illness are discussed.
