Thymoma — Staging and Treatment
ثبت نشده
چکیده
Thymus: This is a part of the immune system that is located in the anterior mediastinum. It is more prominent in children and often extends from 4th costal cartilage to the lower poles of the thyroid gland. It shrinks during adulthood and is slowly replaced by the fat tissue. The thymus plays an important role in the production and maturation of T-lymphocytes that protect the body from various infections.
