title: A malignant Leydig cell tumour associated with testicular trauma and prostatic carcinoma.
abstract: A case of metastatic Leydig cell carcinoma without sex hormone overproduction is reported. The patient had had a prior testicular contusion trauma on the same side after which the testicle had been swollen and firm. The possible aetiological role of extreme trauma is discussed. Radical orchidectomy is recommended for large tumours because of the difficulty in predicting malignant potential, and routine follow-up with retroperitoneal ultrasound scanning for 10 years in all cases.
