Yolk sac tumour of the testis in childhood

Abstract

Despite being a rare neoplasm, yolk sac tumour is the commonest of all childhood testicular malignancies. Early detection and treatment result in an excellent prognosis. Ultrasound can play a valuable role in differentiating benign and malignant forms of testicular pathology at any age. Detailed description of ultrasonic appearances of specific tumours with pathological correlation is, however, as yet incomplete. A 13-month-old child was admitted with a scrotal swelling that was thought by the mother to have been present since birth but had increased considerably in size over the previous 4 weeks. Clinical examination revealed a large, tense, non-tender swelling which did not transilluminate. A complicated hydrocele was suspected.
