We report a case of acrodermatitis chronica atrophicans in an 11-year-
old girl living in an area endemic for Lyme borreliosis. The diagnosis
was first made on the basis of clinical, histopathological and serolo
gical findings, Moreover, Borrelia burgdorferi-specific DNA was amplif
ied from lesional skin by polymerase chain reaction, Intravenous treat
ment with ceftriaxone (2 g once daily) for 2 weeks was initiated, The
skin changes clearly responded to the therapy, and Borrelia burgdorfer
i-specific gene segments were no longer detectable by polymerase chain
reaction. This is the first report of molecular-proven acrodermatitis
chronica atrophicans in childhood, The occurrence of this late skin m
anifestation of Lyme borreliosis in children is reviewed.
