ABSTRACT

Yolk-sac tumor in the testis is a very rare testicular tumor, most of which occurred in young children. Typical microscopic finding of yolk-sac tumor reveals perivascular mantles (Schiller-Duval body) with papillary structure. In the absence of distant metastasis, prognosis of yolk-sac tumor is known to be good. Recently. we experienced a case of yolk-sac tumor of the testis in 19 months male infant who had pulmonary metastasis with poor prognosis.
