Answer 1: B. Placental-like alkaline phosphatase
Answer 2: C. Seminoma
Testicular seminoma is a germ-cell tumor and one of the most common germ-cell tumors of the testis. The tumor can occur in different areas, but usually along the midline. Commonly the patients are asymptomatic.
The tumor appears to be more common in men between 30- and 45-years-old.
Since the tumor can metastasize to lymph nodes, surgical staging is an important prognostic factor and the treatment of these tumors is related to the staging.
The prognosis for patients with pure seminomas limited to the testis is good with a potential cure in about 90% of patients.
