Dt. Uehling et E. Phillips, RESIDUAL RETROPERITONEAL MASS FOLLOWING CHEMOTHERAPY FOR INFANTILE YOLK-SAC TUMOR, The Journal of urology, 152(1), 1994, pp. 185-186
A child treated with chemotherapy for disseminated yolk sac tumor had
a residual retroperitoneal mass after normalization of serum alpha-fet
oprotein. The mass was excised and histologically showed only fibrous
tissue, necrosis and calcification. To our knowledge this is the first
case reported of a prepubertal yolk sac tumor associated with a resid
ual retroperitoneal mass.
