Malignant teratoma in Infant/Neonate
Signs of malignant teratoma depend on the location of the tumor and are usually secondary to mass effect or compression. These tumors may secrete alpha-fetoprotein, but this is not diagnostic.
Malignant teratomas are treated with surgery and chemotherapy. Malignant teratomas discovered at even an advanced stage typically have a good survival rate.
