Fibrinoid necrosis is a type of necrosis that can be seen in blood vessel walls. It is associated with immune-complex vasculitis and hypertenstion. Immune complexes, complement and plasma proteins deposit in damaged vessel walls, giving the tissue a smudgy, bright pink appearance on histological examination.^[1]

Fibrinoid necrosis is a histopathological hallmark of malignant hypertension (blood pressure greater than 200/130 mmHg).^[2]
