How does a laceration differ from a lesion?

A laceration is defined as a tear or cut in the skin or tissue, often resulting from trauma such as an accident or injury. It is characterized by irregular edges and may vary in depth and severity. On the other hand, a lesion refers to any abnormal change in the tissue, which can manifest as a patch, sore, or other form of tissue alteration. Lesions can arise due to various underlying causes, including infections, inflammatory conditions, or tumors, and do not necessarily imply any specific type of injury or trauma. This distinction highlights that while a laceration is a specific type of injury resulting in a disruption of the skin or tissue, a lesion represents a broader category of abnormal tissue changes that might not involve trauma, thus clarifying their individual definitions in medical terminology.
