Skin erosion.

Question

Erosion is a discontinuity of the skin exhibiting incomplete loss of the epidermis, a lesion that is moist, circumscribed, and usually depressed. Ulcer an ulcer is a discontinuity of the skin exhibiting complete loss of the epidermis and often portions of the dermis and even subcutaneous fat. Erosion is different from an ulcer. An "ulcer" is an area of damage to the gastrointestinal wall (in this case the gastric wall) that extends deeper through the wall than an erosion (an ulcer can extend anywhere from beyond the lamina propria to right through the wall, potentially causing a perforation).
