A 60-year-old man was diagnosed as adult T-cell leukemia with severe hypercalcemia because of production of parathyroid hormone-related protein. After admission, the patient had respiratory insufficiency with an infiltrative shadow in his lungs suggestive of pneumonia. However, neither improvement in respiratory function nor disappearance of the abnormal chest shadow was observed with administration of various antibiotics. An autopsy demonstrated the chest shadow had been caused by metastatic calcification associated with hypercalcemia due to production of parathyroid hormone-related protein. The possibility of metastatic calcification should be considered in patients with adult T-cell leukemia and hypercalcemia who have an abnormal chest shadow.

A 69-year-old female was admitted to our hospital because of leg edema, proteinuria (2.1 g/day), and gross hematuria. She had non-alcoholic liver cirrhosis of unknown etiology. Esophageal varices also were found. Examination of the renal biopsy specimen revealed mesangial proliferative glomerulonephritis with IgA deposits. Propranolol was administered orally to reduce portal hypertension, resulting in a progressive decrease in urinary microalbumin excretion. This case suggests that portal hypertension is involved in the pathogenesis of IgA nephropathy in liver cirrhosis.
