Early localized Lyme disease in a pediatric patient: case report.

Lyme disease is an illness caused by species of Borrelia spirochetes. Early diagnosis of lyme disease depends on the recognition of skin findings, which are seen in almost 80% of all cases. Erythema migrans is the most common skin lesion. Serologic tests can be used to support the clinical diagnosis. In this article, we report a six-year-old girl who was diagnosed as having early localized lyme disease, who presented with a rash on her right shoulder. The lesion was found consistent with erythema migrans. She had a history of tick bite seven days before the onset of the rash. Serologic test results were also consistent with lyme disease. Her skin lesion disappeared with cefuroxime treatment, and no additional symptoms or pathologic findings were observed on follow-up. Recognizing early signs is important for prompt diagnosis and treatment to prevent long-term complications because the diagnosis and treatment of late-stage lyme disease can be challenging.
