Which of the following represents an example of metastatic calcification?
End-stage renal failure leads to hyperparathyroidism and secondarily to hypercalcemia. The latter results in metastatic calcification. Old foci of tuberculosis, a calcified mitral valve damaged previously by rheumatic fever, and calcification within breast cancer are all examples of dystrophic calcification.
