A tumor that arises from pluripotent cells containing tissues from all three germ layers is classified as:
- A Hamartoma
- B Teratoma ✓
- C Choristoma
- D Blastoma
Correct answer: B. Teratoma
Explanation
Teratomas arise from pluripotent germ cells and contain differentiated tissues derived from all three germ layers (ectoderm, mesoderm, endoderm). A hamartoma is a disorganized but native tissue overgrowth; a choristoma is a rest of normal tissue in an abnormal location; blastomas resemble embryonic precursor cells of a specific organ.
