He had a history of a stable left testicular mass for 3 years, and a physical exam revealed a non-tender, firm left testicular mass and a mild left varicocele. Testicular tumour markers were normal, but a scrotal ultrasound revealed a 2 cm hypoechoic left testicular lesion. Staging imaging showed no retroperitoneal adenopathy or pulmonary metastases.<\/jats:p>\n               <jats:p>The patient underwent left radical inguinal orchiectomy with no evidence of extratesticular or spermatic cord involvement. His surgical pathology revealed a left pT1a 2.3\u2009cm adult granulosa cell tumour of the testis with no lymphovascular invasion.
