lesioned

This term is primarily used in clinical, pathological, and veterinary contexts to describe tissue that has been damaged or altered by a disease process. It carries a sterile, diagnostic tone and is rarely used in casual conversation, where words like injured or damaged are preferred.

Because it functions as a participial adjective, it describes the state of an organ or area after a lesion has formed. It implies a localized area of abnormal tissue rather than a general state of illness.
