What term describes a mass of necrotic tissue that results from circulatory obstruction?

The term "infarct" refers specifically to a localized area of necrotic tissue that forms when the blood supply to a part of the body is obstructed, typically by a clot or other obstruction in a blood vessel. This deprivation of blood flow leads to a lack of oxygen and nutrients, resulting in tissue death. Infarcts can occur in various organs, such as the heart (myocardial infarction) or the brain (cerebral infarction), and are often associated with serious health conditions.

In contrast, an abscess is a collection of pus that forms in response to infection, gangrene refers to the death of body tissue due to a lack of blood flow or severe bacterial infection, and a vesicle is a small fluid-filled blister or sac that can occur in the skin or mucous membranes. Each of these terms pertains to different pathophysiological processes, which reinforces why "infarct" is the most appropriate term for describing necrotic tissue resulting from circulatory obstruction.
