Approximately 90–95% of testicular cancers are divided into two main categories: seminomas and non-seminomas. Tumors often contain more than one type of tumor cell and are called mixed germ cell tumors. The main types of non-seminoma are embryonal carcinoma, yolk sac carcinoma, choriocarcinoma, and teratoma. Other types are stromal tumors, Leydig cell tumors and Sertoli cell tumors. Secondary testicular cancers are lymphoma, leukemia, and metastases. Sarcomatoid carcinoma tumors in the testicles are very rare. Other case reports have described rare types of testicular cancer, e. g. testicular fusocellular rhabdomyosarcoma, paratesticular liposarcoma, testicular carcinoid, testicular sarcoidosis, testicular clear cell carcinoma, testicular chloroma, cutaneous mucinous carcinoma, and sarcomatoid yolk sac.

When treating testicular tumors, surgery is the primary treatment and adjuvant chemotherapy and radiotherapy may be required. Owing to the aggressive nature of sarcomatoid carcinomas and the high probability of distant metastasis, the prognosis may not be favorable. No other cases of this entity have been reported in the English literature. We hereby present a case of a 62-year-old male patient diagnosed with a testicular metastatic sarcomatoid carcinoma of unknown primary
