Acrodermatitis chronica atrophicans – http://id.who.int/icd/entity/1761234822

This is a late cutaneous manifestation of Lyme borreliosis seen mainly in northern, central and eastern Europe. It presents one or more years after the original infection as an erythematous plaque, which slowly enlarges and gradually becomes violaceous and atrophic. Typical sites are the hands, feet, knees and elbows. Spirochaetes have occasionally been cultured but B. burgdorferi serology is strongly positive in all cases.
