This specialty focuses on diseases of the thymus gland and mediastinum, the area in the chest between the lungs. Pathologists in this field diagnose diseases such as thymomas (tumors of the thymus), lymphomas, and other mediastinal tumors. These diseases are often associated with autoimmune conditions such as myasthenia gravis, so an accurate diagnosis is crucial for planning treatments that may include surgery, radiation therapy, or chemotherapy.
