Most mediastinal malignant tumors are large and cause symptoms by compressing or invading adjacent structures, including the lungs, pleura, pericardium, and chest wall. Seminomas grow relatively slowly and can become very large before causing symptoms. Tumors 20 to 30 cm in diameter can exist with minimal symptomatology.
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.
Although they are often very large tumors (up to 40 cm. in diameter), over half are asymptomatic at diagnosis. [5] While some researchers have proposed that a SFT occupying at least 40% of the affected hemithorax be considered a "giant solitary fibrous tumor", [ 6 ] no such "giant" variant has yet been recognized within the most widely used ...
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 ...
Small cell mesothelioma – an extremely rare subtype of lung cancer – can be mistaken for small cell lung cancer. [10] Small-cell carcinoma is most often more rapidly and widely metastatic than non-small-cell lung carcinoma [11] (and hence staged differently). There is usually early involvement of the hilar and mediastinal lymph nodes. [12]
Primary mediastinal B-cell lymphoma, abbreviated PMBL or PMBCL, is a rare type of lymphoma that forms in the mediastinum (the space in between the lungs) and predominantly affects young adults. [ 1 ] [ 2 ] [ 3 ]
Testicular teratomas present as a palpable mass in the testis; mediastinal teratomas often cause compression of the lungs or the airways and may present with chest pain and/or respiratory symptoms. Some teratomas contain yolk sac elements, which secrete alpha-fetoprotein. Its detection may help to confirm the diagnosis and is often used as a ...
Consideration of surgery is recommended for Stage 1 limited-stage small cell lung cancer patient with a solitary nodule, no hilar or mediastinal involvement, absence of distant metastases, and no contraindications to surgery classified by the TNM staging system. [18] Surgery is normally followed by chemotherapy.
