Sa. Macdiarmid et Rw. Norman, EXTRAGONADAL NONSEMINOMATOUS GERM-CELL TUMOR WITH HYPERCALCEMIA, MASQUERADING AS RENAL-CELL CARCINOMA - A CASE-REPORT, CAN J SURG, 38(1), 1995, pp. 80-82
Humoral hypercalcemia secondary to the production of parathyroid hormo
ne-related peptide has been reported to occur in up to 17% of patients
with renal cell carcinoma but has been reported only rarely in patien
ts with other genitourinary cancers and never in patients with testicu
lar or extragonadal nonseminomatous cancers. A 54-year-old man is repo
rted who had an extragonadal nonseminomatous germ cell tumour with hyp
ercalcemia that masqueraded as a renal cell carcinoma with metastases.
The hypercalcemia was suspected to be humorally mediated.
