Question 2-year-old boy with right testicular enlargement

A 2-year-old boy was admitted to our hospital with a 2-month history of right testicular enlargement. The boy had no local pain but had repeated fever, the highest rectal temperature being 39.8C. At physical examination, an enlarged right testis with no tenderness was palpable. The testis did not transilluminate. The overlying skin showed no redness or thickening. Laboratory examination revealed a markedly elevated serum alpha-fetoprotein level of 4,396 ng/ml (normal, <20 ng/ml). Sonograms showed an ovoid, homogeneous, isoechoic solid mass in the right testis. What is the most likely diagnosis?

A) Seminoma
B) Embryonal carcinoma
C) Yolk sac tumor
D) Teratoma
E) Choriocarcinoma
F) Sertoli cell tumor
G) Leydig cell tumor
