Yolk Sac Tumour of the Penile Shaft: A Rare Primary Extra-Gonadal Presentation

Afr J Paediatr Surg. May-Aug 2011;8(2):241-3. doi: 10.4103/0189-6725.86074.


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.
