Ulcer

An ulcer (from Latin ulcus) is an open sore of the skin, eyes or mucous membrane, often caused by an initial abrasion and generally maintained by an inflammation and/or an infection.

Other locations

• Inferior members: most ulcers of the foot and leg are caused by underlying vascular insufficiency. The skin breaks down or fails to heal because of repeated insult or trauma. Pressure of the nail can cause subungual ulceration. These are most frequently seen in diabetics who have a very low potential to heal from injury.
• Sacrum and ischium
• Mouth ulcer
• Intestinal ulcers: This includes ulcers of the esophagus, stomach, large and small intestine
• Genitalia: May be penile, vulvar or labial. Most often are due to sexually-transmitted diseases
• Eyes: corneal ulcers are the most common type. Conjunctival ulcers also occur.
