Approximately 25% to 35% of these are on the heels. those with peripheral vascular disease are at high risk. These may also be seen on the sacrum, knees. ankles, pinna of the ears, elbows. What is this?

A. Candida albicans is a fungal infection typically found in moist skin folds, not commonly on the heels, sacrum, or bony prominences. B. Melanoma is a type of skin cancer that presents as an abnormal mole or pigmented lesion, not pressure-related ulcers. C. Keratosis refers to a skin condition involving thickened skin (e.g., seborrheic or actinic keratosis) and is unrelated to pressure or vascular disease. D. Pressure injuries (also known as pressure ulcers or bedsores) often occur on bony prominences like the heels, sacrum, elbows, knees, and ears. People with peripheral vascular disease are at increased risk due to poor circulation and impaired healing, and 25–35% occur on the heels, making this the correct answer.
