Early-stage thymic carcinoma is generally asymptomatic, and the development of symptoms is indicative of an advanced stage cancer. [3] Signs and symptoms are non-specific and include chest pain, persistent cough, and difficulty breathing, which are related to progressive tumor compression of anterior chest wall structures. [4]
A third of all people with a thymoma have symptoms caused by compression of the surrounding organs by an expansive mass. These problems may take the form of superior vena cava syndrome, dysphagia (difficulty swallowing), cough, or chest pain. [2] One-third of patients have their tumors discovered because they have an associated autoimmune disorder.

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]
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.
Ectopic thymus is a condition where thymus tissue is found in an abnormal location . It usually does not cause symptoms, but may leads to a mass in the neck that may compress the trachea and the esophagus. It is thought to be the result of either a failure of descent or a failure of involution of normal thymus tissue.
PMLBCL arises from a putative thymic peripheral B cell. [6] [7] It has several distinctive biological features. [6] Molecular analysis shows that PMLBCL is distinct from other types of diffuse large B-cell lymphomas (DLBCL). [7] MAL gene expression is seen in 70%, unlike other diffuse large B-cell lymphomas.
Signs and symptoms are not mutually exclusive, for example a subjective feeling of fever can be noted as sign by using a thermometer that registers a high reading. [7] Because many symptoms of cancer are gradual in onset and general in nature, cancer screening (also called cancer surveillance) is a key public health priority. This may include ...
