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.
We describe a primary penile yolk sac tumor in a child with achondroplasia.
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.

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。
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。
