Overview
Natural History, Complications, and Prognosis
Natural History
- The course of acrodermatitis chronica atrophicansis is chronic and could lasts for several years. [1]
- It usually involves extensor surfaces of the acral regions of limbs.[1]
- Skin changes first appear as blue and red discoloration with boggy infiltration. These skin lesions can become atrophic later.
- Based on two studies, 55% and 66% of patients with acrodermatitis chronica atrophicans have at least one history of tick bite, while others may never remember such an accident. Since there could be several years between the tick bite and development of skin lesions, absence of tick bite in patients' history is not meaningful alone.[2]
- One fifth of the patients in a study experienced erythema migrans 6 months to 8 years before acrodermatitis chronica atrophicansis development.[2][3]
Complications
- Common complications of acrodermatitis chronica atrophicansis include:[1]
- Sclerotic skin changes
Prognosis
- Acrodermatitis chronica atrophicansis can lead to extensive atrophy of skin and, in some patients it can cause limitation of upper and lower limb joint mobility.
- The general pognosis is good with proper and rapid treatment in acute inflammatory stage of acrodermatitis chronica atrophicansis.
- The therapeutic outcome is difficult to assess in patients with the chronic atrophic phase because most changes are only partially reversible.
