A tracheal tumor is a tumor primarily presenting in the trachea. It may be benign or malignant. [1] 80% of all tracheal tumors are malignant. Among these, the most common are the squamous-cell carcinoma and the adenoid cystic carcinoma.
Lymph: A clear or white fluid that travels through vessels, moves within tissues and work to keep all the parts of the body clean. Vascular: The body's network of blood vessels. When cancer spreads to lymph and vascular system, it is thus termed as Lymphovascular Invasion.
Fluid in space between the lung and the chest wall is termed a pleural effusion. There needs to be at least 75 mL of pleural fluid in order to blunt the costophrenic angle on the lateral chest radiograph and 200 mL of pleural fluid in order to blunt the costophrenic angle on the posteroanterior chest radiograph. On a lateral decubitus, amounts ...
[3] [15] The trachea and bronchi have plexuses of lymph capillaries in their mucosa and submucosa. The smaller bronchi have a single layer of lymph capillaries, and they are absent in the alveoli. [16] The lungs are supplied with the largest lymphatic drainage system of any other organ in the body. [17]
A vascular tumor is a vascular anomaly where a tumor forms from cells that make blood or lymph vessels; a soft tissue growth that can be either benign or malignant. [1] Examples of vascular tumors include hemangiomas, hemangioendotheliomas, Kaposi's sarcomas, angiosarcomas, and hemangioblastomas. An angioma refers to any type of benign vascular ...
Breast cancer may invade directly through local spread, and through lymph node metastases. After metastasis to the liver, colon cancer frequently metastasizes to the lung. Prostate cancer, germ cell cancer and renal cell carcinoma may also metastasize to the lung. [citation needed] Treatment of respiratory system cancer depends on the type of ...
In humans, the left and right lungs are completely separated by the mediastinum, and there is no communication between their pleural cavities.Therefore, in cases of a unilateral pneumothorax, the contralateral lung will remain functioning normally unless there is a tension pneumothorax, which may shift the mediastinum and the trachea, kink the great vessels, and eventually collapse the ...
Structures within the thoracic cavity include: structures of the cardiovascular system, including the heart and great vessels, which include the thoracic aorta, the pulmonary artery and all its branches, the superior and inferior vena cava, the pulmonary veins, and the azygos vein
