Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Seminoma is a common testicular germ cell tumor in young adult males. It usually presents as a painless testicular mass and is classically homogeneous and non-hemorrhagic.
Step 1: Identify the clinical presentation.
A painless testicular mass in a young adult male suggests a testicular tumor.
Step 2: Identify gross features.
Seminoma is usually: \[ \text{Well-circumscribed + homogeneous + non-hemorrhagic} \]
Step 3: Compare with other tumors.
Choriocarcinoma is often hemorrhagic. Yolk sac tumor is common in children. Teratoma usually contains multiple tissue elements. Therefore, the correct answer is Seminoma.
