How does a teratoma get teeth?
Teratomas can grow teeth, not through dark magic, but through the normal magic of germ cells — the type of stem cell that turns into an egg or sperm cell, which in turn can produce a fetus. Germ cells are “pluripotent,” as scientists put it, which means they can produce all different types of tissue.
Can a teratoma have a heart?
Pericardial teratomas are rare tumors that arise from the sac lining of the heart. They can grow rapidly, leading to pericardial effusion and an in utero cardiac tamponade physiology. Massive growth of the tumor compresses the heart, leading to fetal hydrops and death.
