A lesion is any area of tissue that has been damaged or has changed from its normal appearance.
Lesions may result from injury, infection, inflammation, congenital conditions, or disease. They can occur anywhere in the body and vary in size, shape, colour, and severity.
In dermatology, a lesion refers to any abnormal area of skin, including a rash, papule, blister, ulcer, or mole.
