Lyme disease is caused by Borrelia burgdorferi infection which is transmitted by Ixodes ricinus. Erythema migrans, a rash spreading from the site of a tick bite, is the earliest and most common manifestation of the disease. If untreated, late manifestations of disseminated disease, mainly neurological and musculoskeletal, may occur. Serologic studies are usually negative in early stages and are not necessary to confirm the diagnosis in cases of erythema migrans. Laboratory confirmation is needed for disseminated disease. Most presentations, including facial nerve palsy, can be treated with oral antibiotics. Ceftriaxone is recommended in other cases of neuroborreliosis. Four cases of Lyme disease in children are reported to illustrate the different presentations of this disease and its management in children.
