What is the term for staining caused by prolonged contact with pressure, commonly affecting the skin?

The term that describes staining resulting from prolonged pressure on the skin is "bedsores." These lesions occur when blood flow to a particular area of the skin is restricted as a result of sustained pressure, often from lying or sitting in one position for too long. Bedsores, also known as pressure ulcers or decubitus ulcers, can cause damage to the skin and underlying tissues, leading to discoloration, tissue breakdown, and in severe cases, infections.

Understanding that bedsores are specifically linked to pressure reveals why they have this designation. They most commonly develop in areas where bone is close to the skin, such as the heels, elbows, and the tailbone. The prolonged pressure disrupts blood flow, causing the skin to become red or discolored. If not managed appropriately, this can progress to more serious stages where the skin may break down completely.

In contrast, calluses are thickened areas of skin that develop as a response to friction or pressure over time but do not involve tissue damage or blood flow issues like bedsores. Wounds generally refer to injuries where the integrity of the skin is compromised, such as cuts or abrasions, but do not specifically relate to pressure. Ulcers, while they can refer to various types
