The wounds from which<unk> s arise can be caused by a wide variety of factors, but the main cause is impaired blood circulation. Especially, chronic wounds and<unk> s are caused by poor circulation, either through cardiovascular issues or external pressure from a bed or a wheelchair. A very common and dangerous type of skin<unk>  is caused by what are called pressure-sensitive sores, more commonly called bed sores, which are frequent in people who are bedridden or who use wheelchairs for long periods. Other causes producing skin<unk> s include bacterial and viral infections, fungal infections and cancers. Blood disorders and chronic wounds can result in skin<unk> s as well. Venous leg<unk> s due to impaired circulation or a blood flow disorder are more common in the elderly. Rare causes of skin<unk> s include pyoderma gangraenosum, lesions caused by Crohn's disease or<unk> ative colitis, granulomatosis with polyangiitis, morbus Behçet and infections that are usually seen in those who are immunocompromised, for example ecthyma gangraenosum. It is important to consider such causes if the skin<unk> ations don't show improvement with antibiotic treatments and when other systemic symptoms are present. It is advised not to use surgical procedures on<unk> ations caused by Behçet or pyoderma gangraenosum since those diseases usually exhibit pathergy.
