    B]Placental alkaline phosphatase:correct answer
    The polygonal cells with clear cytoplasm in lobules and surrounded by fibrous is the feature of the most common testicular cancer "Seminoma"....in which the placental alkaline phosphate is increased.

    A]PSA is increased in prostate ca

    C]AFP is increased in embryonal ca or yolk sac tumor of testis

    D]HCGincreased in chorio ca of testis

    and in real life you ALWAYS. A-L-W-A-Y-S rule out nonseminomatous component by ordering AFP. if its positive you assume there is a nons component and treat as such. or you are big trouble.

    also PAP may be rasied but it may not and it doesnt tell you much if it is. the important thing is being AFP negative.

    there is a similiar question to this in UW but has thyroid component to it. Since HCG is analog to TRH, LH, and FSH that is why u will have thyroidism related to HCG. However, since this question doesnt have any thyroid component to it, i will go with AFP.
