Background: This article reports partial orchidectomy for malignant tumour in a solitary testis and discusses the common occurrence of carcinoma in situ (CIS) in the non‐tumour part of a testis containing malignant tumour, or in 5% of the contralateral testis when malignant tumour is found in one testis. Method: Ultrasound of the testis gave the appearance of a 21‐mm germ cell tumour in the lower pole of a solitary testis in a 20‐year‐old man. Chest X‐ray was clear, and blood testis tumour markers were negative. Semen was collected and stored under liquid nitrogen freezing. The testis was explored through a groin incision and then the palpable tumour together with a margin of normal‐looking testis was excised. Results: Histology showed embryonal carcinoma with no CIS in the adjacent normal testis tissue that had been excised with the tumour. At 93 months postoperatively, computed tomography scans of the chest and abdomen were negative, as were blood testis tumour markers, and the patient is potent. Ultrasound shows a testis of normal size and consistency. Conclusion: Partial orchidectomy was practical in this case, but CIS is common in the non‐tumour part of any testis containing germ cell tumour and should be searched for histologically. In a man with two testes, one containing a germ cell tumour, CIS is found in 5% of the contralateral testes. Testis CIS leads to invasive carcinoma within 5 years in 50% of cases. When CIS is present, local radiation therapy is recommended by Heidenreich et al. ; this retains potency but destroys fertility. Some are treating with chemotherapy CIS or germ cell primary tumours other than teratoma, in an attempt to preserve both potency and fertility.
