Ulcer treatment. Dressed and bandaged ulcer on an elderly male patient's arm. Ulcers are open wounds or lesions in the skin which become inflamed and fail to heal properly. They can form as a result of vascular disorders where abnormal blood circulation results in inflamed and dying tissues. Images M729/033 and M729/034 show earlier stages of wound care.
