The spectrum of
skin manifestations of
Lyme borreliosis in children is not well characterized. We conducted a retrospective study to analyze the clinical characteristics, seroreactivity to Borrelia burgdorferi sensu lato, and outcome
after treatment in 204 children with
skin manifestations of
Lyme borreliosis seen in 1996-2011. Solitary
erythema migrans was the most common manifestation (44.6%), followed by
erythema migrans with multiple lesions (27%), borrelial
lymphocytoma (21.6%), and
acrodermatitis chronica atrophicans (0.9%). A collision lesion of a primary borrelial
lymphocytoma and a surrounding secondary
erythema migrans was diagnosed in 5.9% of children. Rate of seroreactivity to B. burgdorferi s.l. was lower in solitary
erythema migrans compared to other diagnosis groups.
Amoxicillin or
phenoxymethylpenicillin led to complete resolution of
erythema migrans within a median of 6 (solitary) and 14 days (multiple lesions), respectively, and of borrelia
lymphocytoma within a median of 56 days. In conclusion,
erythema migrans with multiple lesions and borrelial
lymphocytoma appear to be more frequent in children than in adults, whereas
acrodermatitis chronica atrophicans is a rarity in childhood. The outcome after
antibiotic therapy was excellent in children, and appears to be better than in adults.
