Extragonadal primary tumors are uncommon and account for 3 to 5% of all germ cells neoplasias. Preferentially found in middle line structures, such tumors are frequently in an advanced stage when diagnosed. Differentiation between primary extragonadal tumors and metastasis of testicular primary tumors is essential, but may be difficult in many instances.
性腺外原发性肿瘤并不常见，占所有生殖细胞肿瘤的3%至5%。这类肿瘤多位于中线结构，确诊时往往已处于晚期。区分原发性性腺外肿瘤和睾丸原发性肿瘤的转移至关重要，但在很多情况下可能存在困难。
