A study examining cases of thymic carcinoma in the United States from 2001 to 2015 found a peak incidence from 70 to 74 years old and a higher incidence in males compared to females. After thymoma, thymic carcinoma is the second most common type of thymus cancer. [2]
A thymoma is a tumor originating from the epithelial cells of the thymus that is considered a rare neoplasm. [1] Thymomas are frequently associated with neuromuscular disorders such as myasthenia gravis; [2] thymoma is found in 20% of patients with myasthenia gravis. [3] Once diagnosed, thymomas may be removed surgically.

It contains the heart, esophagus, trachea, thymus, and aorta. The most common mediastinal masses are thymoma (20% of mediastinal tumors), usually found in the anterior mediastinum, followed by neurogenic Timor (15–20%) located in the anterior mediastinum. [1] Lung cancer typically spreads to the lymph nodes in the mediastinum.
Thymoma is a common neoplasm arising from the thymus, the primary lymphoid organ where T cells become educated to distinguish "self" from "non self". In the setting of thymoma, abnormal thymic education occurs as a result of subtle differences in antigen processing. In TAMA these differences result in autoreactive T cells escaping from the thymus.
The thymus may contain cysts, usually less than 4 cm in diameter. Thymic cysts are usually detected incidentally and do not generally cause symptoms. [3] Thymic cysts can occur along the neck or in the chest (mediastinum). [26] Cysts usually just contain fluid and are lined by either many layers of flat cells or column-shaped cells. [26]
If cells do not receive sufficient stimulation, they enter apoptosis: so-called death by neglect. Next, single-positive (SP) cells enter the thymic medulla and interact with self-antigens expressed on medullary thymic epithelial cells. The expression of otherwise tissue-restricted self antigens is mediated by AIRE and Fezf2.
The following is a list of cancer types. Cancer is a group of diseases that involve abnormal increases in the number of cells , with the potential to invade or spread to other parts of the body. [ 1 ]
