L90: Atrophic disorders of skin

L90.4: Acrodermatitis chronica atrophicans

You have a skin condition that has been caused by certain pathogens. These pathogens can be transmitted by ticks, for example. You were infected by these pathogens some months or years ago. Your skin has become inflamed in certain places as result. The skin may then become somewhat thinner and turn blue, for example. The skin in those places is sometimes susceptible to injury. The person may also no longer be able to feel touch properly in the affected areas.
