Necrosis

A type of cell death. As opposed to apoptosis which can be normal or abnormal, necrotic cell death is almost always abnormal. Common types of necrosis include coagulative necrosis (e.g. tumor necrosis), liquefactive necrosis (e.g. in brain post injury), caseous necrosis (grossly looks cheese-like and may be due to underling tuberculosis or fungal infection), fat necrosis, and hyaline vascular necrosis
