چکیده
Teratomas are germ cell tumors. Mediastinum is the second most common extra-gonadal site of these tumors.[1-3] Mediastinal masses in children and adolescents are usually considered malignant. Even benign teratomas have been reported to transform to malignant ones in case of delayed diagnosis or presentation.[3-5] Moreover, large mediastinal teratoma without any long-term symptomatology is quite rare. We describe here a large anterior mediastinal mature teratoma diagnosed in a paucisymptomatic adolescent.
