The formation of excessive fibrous tissue, as in a reparative or reactive process. 1. the process of forming fibrous tissue, usually by degeneration (for example, fibrosis of the pulp). The process occurs normally in the formation of scar tissue to replace normal tissue lost through injury or infection. 2. an abnormal condition in which fibrous connective tissue spreads over or replaces normal smooth muscle or other normal organ tissue. Fibrosis is most common in the heart, lung, peritoneum, and kidney.
