Yolk sac tumor (YST) of testis is the most common of all childhood testicular malignancies. We report a case of testicular YST in a 2‐year‐old boy. The tumor appeared sonographically as an ovoid, homogeneous, well‐circumscribed, isoechoic, solid testicular mass with good sound‐through transmission and increased internal vascularity on color Doppler imaging. The serum alpha‐fetoprotein level was 4,396 ng/ml. Pathological examination confirmed YST at at stage I. Although the sonographic appearance of YST of the testis is nonspecific, the diagnosis is achievable in clinical practice on the combination of elevated serum alpha‐fetoprotein level and sonograms depicting a solid testicular hypervascular mass. © 2006 Wiley Periodicals, Inc.
