Hypercalcaemia and phaeochromocytoma

A patient with a phaeochromocytoma associated with hypercalcemia is described. The hypercalcaemia was corrected by removal of the phaeochromocytoma. Parathyroid hormone-like peptide was isolated from the tumour suggesting that ectopic parathyroid hormone production from the phaeochromocytoma was the explanation of the hypercalcaemia.
