Which ovarian tumor is characterized histologically by Schiller-Duval bodies and produces AFP?
- A Yolk sac tumor ✓
- B Embryonal carcinoma
- C Choriocarcinoma
- D Immature teratoma
Correct answer: A. Yolk sac tumor
Explanation
Schiller-Duval bodies (perivascular formations with a central vessel) are pathognomonic for yolk sac tumor (endodermal sinus tumor), which characteristically produces AFP. Choriocarcinoma produces beta-hCG. Embryonal carcinoma has solid sheets of pleomorphic cells without Schiller-Duval bodies. Immature teratoma contains immature neuroectoderm.
