A lesion is any abnormal damage or change in the tissue of an organism , usually caused by disease or trauma . Lesion is derived from the Latin word "laesio", meaning injury . Lesions may occur in plants as well as animals.
In this website, we will prefer the word " anomaly " to the word " lesion ", because this last word implied a damage by a cause , that is not always present.
