BACKGROUND
Yolk sac tumors (YST) are commonly encountered gonadal germ cell tumors in children, especially in the prepubertal age group. In addition to gonadal primary, it can occur in multiple extragonadal sites, of which sacrococcygeal, retroperitoneum, gastric and mediastinum are the commonest. There are 4 previous reports of primary penile YST.
CASE REPORT
We describe a primary penile yolk sac tumor in a child with achondroplasia.
CONCLUSION
Yolk sac tumor can occur in the penis during the prepubertal period. Penile yolk sac tumor associated with achondroplasia has not been previously reported, but this could be incidental.
背景
卵黄囊瘤（YST）是儿童常见的性腺生殖细胞肿瘤，尤其多见于青春期前。除了性腺原发外，也可发生于多个性腺外部位，其中最常见的是骶尾部、腹膜后、胃和纵隔。此前已有 4 例原发性阴茎卵黄囊瘤的报告。
病例报告
我们描述了一例患有软骨发育不全的儿童的原发性阴茎卵黄囊瘤。
结论
卵黄囊瘤可发生于青春期前的阴茎。与软骨发育不全相关的阴茎卵黄囊瘤此前尚未报道，但这可能是偶然的。
