Except for the inconsistency with histologic results, the characteristics of the present case for the most part resembled those of extra-gonadal NSGCT: 1) occurrence in young adults, mostly males; 2) midline location; 3) metastases to the lungs, liver, and bones; and 4) elevated serum tumor markers (AFP and hCG) [7]. This evidence concerns the gene AFP and nongerminomatous germ cell tumor.
