Hyperplasia

 

an increase in the number of structural elements of tissues or organs. In man and animals, hyperplasia is based on the intensified reproduction of cells and the formation of new structures. Hyperplasia is observed in various types of pathological growth of tissues (chronic productive inflammation and tumor), in regeneration, and in hypertrophy.

The result of hyperplasia is the formation of galls, calluses, and warts.
