The pathophysiology and clinical characteristics of severe hypophosphatemia;Knochel, J.P.;Arch Intern Med; Sir, Occult malignancy may present as hypercalcaemia and increased levels of parathyroid hormone-related protein (PTHrp), as recently reported in the Journal by Hutchesson et al.' Only six patients with oesophageal carcinoma presenting as hypercalcaemia have been reported. Only one patient had no local obstructing symptoms or bone metastasis, and serum parathyroid hormone was found to be mildly elevated.2 We report a patient with squamous cell carcinoma of the oesophagus (SCCE) and no obstructing symptoms, presenting as malignant hypercalcaemia, with intact parathyroid hormone (iPTH) suppressed, and increased PTHrp,1977
