Where is the thymus gland located in mediastinum?
The thymus is located in the upper front part of the chest, in the anterior superior mediastinum, behind the sternum, and in front of the heart. It is made up of two lobes, each consisting of a central medulla and an outer cortex, surrounded by a capsule.
Can T cells mature without a thymus?
Children born without a thymus because of an inability to form a proper third pharyngeal pouch during embryogenesis (DiGeorge Syndrome) were found to be deficient in T cells. Of several different T cell deficiencies that have been identified in mice, two complementary defects are found in SCID and nude mice.
Where is the thymus gland located in the body?
Sometimes, however, the thymus gland is found in another (ectopic) location, such as in the neck, the thyroid gland, or on the surface of the lungs (the pleura) near the area where the blood vessels and bronchi enter the lungs. It is named the thymus due to its shape being similar to that of a thyme leaf—pyramid-shaped with two lobes.

Where are the mediastinal lymph nodes located in the heart?
They surround the pericardium, thymus, and the major vessels of the heart. The posterior mediastinal lymph nodes are located posterior to the heart and anterior to the spinal column.
What are the histopathological features of mediastinum and thymus?
The histopathological features are similar as discussed above. Organisms may be demonstrated by acid fast or fungal stains In sarcoidosis, mediastinal lymph nodes are enlarged by nonnecrotizing granulomas. Stains for microorganisms are negative, and granulomas are confined within the capsule of the lymph node
