Pure testicular teratomas are exceptionally rare among nonseminomatous germ cell tumors (NSGCT). Despite their limited chemosensitivity, upfront chemotherapy is recommended for metastatic patients due to the potential presence of another NSGCT subtype alongside teratoma in metastases. We present a case report of a patient with primary post-pubertal teratoma and retroperitoneal cystic metastases, along with negative serum tumor markers - an exceedingly rare clinical scenario. In such cases, cystic retroperitoneal metastases are highly likely to be formed by teratoma, making primary retroperitoneal lymph node dissection a preferred option over chemotherapy, which would be ineffective in such a patient.
