Back pain--a presentation of metastatic testicular germ cell tumours.

9 patients (21%) from a total of 42 young men with testicular germ cell malignancy had back pain as a major presenting symptom; 2 had back pain without unilateral testicular enlargement. Time to correct diagnosis from first visit to a doctor was significantly longer in those with back pain than in those with testicular symptoms. All patients with back pain had para-aortic node metastases. Young men with back pain should be examined for testicular disease and should also be asked about past testicular abnormalities.
