RESUMEN
Metastatic calcification is the deposition of calcium salts in previously healthy tissues, usually as a result of abnormalities of calcium and phosphorous metabolism. The pulmonary parenchyma is most susceptible to calcification. Such condition may be caused by both benign and malignant diseases, most commonly metastatic pulmonary calcification is seen in patients with chronic renal failure who are on hemodialysis. In autopsies, 60-80% of patients with CRF reportedly present MPC[1] We report two cases with chronic renal failure and metastatic calcifications, both patients were hypertensive and were on dialysis. A 46 yrs old female suffering from chronic renal failure, is on dialysis for 2 years. Another patient 48 yrs old was a known case of chronic renal failure. She is on dialysis for 6 years
