Note that lesions are not limited to animals or humans; damaged plants are said to have lesions.
An additional classification that is sometimes used is based on whether or not a lesion occupies space. A space occupying lesion, as the name suggests, occupies space and may impinge on nearby structures, whereas a non space occupying lesion is simply a hole in the tissue, e.g. a small area of the brain that has turned to fluid following a stroke.
Some lesions have specialized names, like the Gohn lesions in the lungs of tuberculosis victims. The characteristic skin lesions of a varicella-zoster virus (VZV) infection are called chickenpox. Lesions of the teeth are usually called dental caries.
Finally, lesions are often classified by their location. For example, compare a 'skin lesion' versus a 'brain lesion'.
