title: Extragonadal nonseminomatous germ cell tumour with hypercalcemia, masquerading as renal cell carcinoma: a case report.
abstract: Humoral hypercalcemia secondary to the production of parathyroid hormone-related peptide has been reported to occur in up to 17% of patients with renal cell carcinoma but has been reported only rarely in patients with other genitourinary cancers and never in patients with testicular or extragonadal nonseminomatous cancers. A 54-year-old man is reported who had an extragonadal nonseminomatous germ cell tumour with hypercalcemia that masqueraded as a renal cell carcinoma with metastases. The hypercalcemia was suspected to be humorally mediated.
