Lyme disease in childhood: report of one case.

We report a pediatric patient of Lyme disease in Taiwan, confirmed by laboratory tests. An 8-year-old overseas Chinese girl from New Jersey, USA, visited our dermatological clinic with joint pain and multiple expanding annular erythema rashes (measured up to 17x10 cm) for three days. Lyme disease was diagnosed by the presence of the antibody against Borrelia burgdorferi. The skin lesions and arthralgia were resolved after amoxicillin treatment, and she got well in the following one year. This presented work tries to remind physicians to be aware of Lyme disease in Taiwan, particularly for children or young people with recurrent expanding annular skin rashes and chronic arthralgia of undetermined causes.
