Yolk sac tumour of testis (YSTT) is an aggressive neoplasm that resembles the allantois of the embryo and becomes a difficult diagnosis in children, even in a pure form. We present the case of a-16 year-old boy with a right scrotal swelling and haematocele that revealed due to microscopic examination a hepatoid-microcystic YSTT on a small testicular biopsy. The serum alpha-feto-protein (AFP) showed detectable levels as high as 3,7 ng/L, with negative values for β-hCG and CEA 125.
