Explanation

An ulcer is fundamentally a break or sore in the epithelial lining. This can occur on the skin (like bed sores or diabetic foot ulcers) or in the mucous lining of internal organs (like peptic ulcers in the stomach/duodenum). Both manifestations involve tissue breakdown and impaired healing, whether external (skin) or internal (organ lining).
