Germ cell tumours (GCTs) commonly involve the ovaries, testes, and other midline structures in children and adolescents and comprised a variety of tumours that have a common histiogenetic origin. The yolk sac tumour (YST) variant is the most common one seen in over 80% of testicular GCTs in children. Other sites of occurrence of these tumours include the mediastinum, prostate, retroperitoneum, and sacrococcygeal region. Penile malignancies account for less than 10% of male malignancies in the elderly, while its occurrence in children is rare. We present the case of a 5-year-old child with YST of the penile shaft and uninvolved testes.
生殖细胞肿瘤（GCTs）常见于儿童和青少年的卵巢、睾丸及其他中线结构，由多种具有共同组织发生起源的肿瘤组成。卵黄囊瘤（YST）变体是儿童睾丸GCTs中最常见的一种，超过80%的病例可见。这些肿瘤的其他发生部位包括纵隔、前列腺、腹膜后和骶尾部区域。阴茎恶性肿瘤在老年男性恶性肿瘤中占比不到10%，而在儿童中罕见。我们报告一例5岁儿童阴茎干卵黄囊瘤且睾丸未受累的病例。
