Erosion is a term that has meaning in several different disciplines, e.g. geography.
In terms of medicine, the term 'erosion' refers to the 'eating away' of surface tissue - by chemical or physical processes, such as due to inflammation. In purely physical terms, 'erosion' can also be defined as a loss of epidermis above the basal layer, leaving denuded surface.
Erosion of the skin is a superficial form of ulceration and usually heals quite readily. Another medical use of the term 'erosion' is concerned with loss of surface tooth substance in dentistry.
Erosion is included in this section because it is a type of skin lesion. Study of skin lesions is required as part of many courses in aspects of health and holistic therapies, especially bodywork therapies.
