A lesion is bodily tissue which has been structurally changed due to disease or injury and usually occurs as or includes a fissure, wound, or other break in the tissue. Lesions can occur in various parts of the body such as the skin and other organs.
The simplest definition is "a wound or injury".
Skin lesions are abnormal growths or areas of skin that do not resemble the normal skin surrounding them. Examples include cysts, nodules, papules, polyps, pustules, vesicles and wheals. Lesions not caused by injury can potentially be malignant, so always have any unusual lesions assessed by your doctor.

Always read and understand the Safety Data Sheets for materials you are working with before using them for the first time. Exposure to corrosive chemicals and irritants can cause skin lesions (wounds), while others can cause lesions, tumors or ulcers on the internal organs on chronic (long-term) exposure.
Section 11 (toxicological information) of the SDS will warn you of symptoms of exposure to the material you are working with. Take steps to minimize your exposure to all chemicals and know the hazards of those that you work with. Be sure to use proper engineering controls such as ventilation or fume hoods if available, and personal protective equipment such as gloves or chemical protective clothing. Specific measures will be found in Section 8 (exposure controls/personal protection) of the SDS.
