What is a common subtype of testicular germ cell tumours?

• A. Embryonal carcinoma
• B. Seminoma
• C. Yolk sac tumour
• D. Choriocarcinoma

Answer: (B)

Testicular germ cell tumors are grouped into seminomatous and non-seminomatous types. Seminoma is the most common histologic subtype seen in adults, typically presenting as a painless testicular mass and having a favorable prognosis with appropriate treatment. The other options—embryonal carcinoma, yolk sac tumor, and choriocarcinoma—are non-seminomatous subtypes, which occur but are not as common as seminoma as the single dominant histologic category. So seminoma is the best answer.
