A leg ulcer is simply a break in the skin of the leg which is taking longer than normal to heal.
The immediate cause is usually a minor injury to the skin. In most people such an injury will heal up without difficulty within a week or two. However, if there is an underlying problem the skin does not heal and the area of breakdown may even increase in size. This is a chronic leg ulcer.
Investigation of leg ulcers involves ultrasound scanning of veins and sometimes arterial imaging. Treatment may be compression, laser or surgery.
