Abstract

Vasculitis of the skin (cutaneous vasculitis) is defined as inflammatory cell-mediated destruction of the<br/>vessels of the skin. Small vessels are predominantly affected (arterioles, capillaries, and venules), but<br/>occasionally also medium size arteries. Typical clinical signs of cutaneous vasculitis include purpura, livedo<br/>racemosa and urticaria; moreover, destruction of the vessel walls and subsequent ischaemia can result in<br/>the development of necrosis and an ulcer.<br/>Diagnosis of cutaneous vasculitis should be confirmed by histopathological analysis, and the aetiology of<br/>the vasculitis and the possibility of the presence of systemic disease should be assessed. Mild vasculitis<br/>of the skin without evidence of systemic disease may improve even without treatment, whereas patients<br/>with vasculitic ulcers should be treated by dermatologists specialized in the treatment of atypical ulcers.<br/>Often a multidisciplinary team is also needed. The treatment should be tailored individually taking into an<br/>account the aetiology of the vasculitis, the patient’s comorbidities, other medications and the severity of<br/>the cutaneous manifestations.<br/>The prognosis of cutaneous vasculitis varies and is dependent on the manifestation, aetiology and severity<br/>of this disease. Most patients diagnosed as having cutaneous vasculitis have mild and self-limiting<br/>disease, but cutaneous vasculitis may also lead to amputation of a limb or at worst even to death. Disease<br/>recurrences can also occur.
