When it does metastasize, the most commonly involved organs are the lungs, brain, bone and other skin locations. [63] Squamous-cell carcinoma occurring in immunosuppressed people (such as those with organ transplant, human immunodeficiency virus infection, or chronic lymphocytic leukemia) the risk of developing cSCC and having metastasis is ...
Chest trauma, a major cause of subcutaneous emphysema, can cause air to enter the skin of the chest wall from the neck or lung. [9] When the pleural membranes are punctured, as occurs in penetrating trauma of the chest, air may travel from the lung to the muscles and subcutaneous tissue of the chest wall. [9]
Squamous-cell carcinoma of the lung is closely correlated with a history of tobacco smoking, more so than most other types of lung cancer.According to the Nurses' Health Study, the relative risk of SCC is approximately 5.5, both among those with a previous duration of smoking of 1 to 20 years, and those with 20 to 30 years, compared to never-smokers.

If the cause is unknown, it is specified and called "simple pulmonary eosinophilia". Cardiac damage caused by the damaging effects of eosinophil granule proteins (e.g. major basic protein ) is known as Loeffler endocarditis and can be caused by idiopathic eosinophilia or eosinophilia in response to parasitic infection.
Schamberg's disease is a skin disorder that causes a discoloration of the lower extremities. [4] It usually occurs in the lower extremities and rarely elsewhere. [4] This condition is caused by leaky blood vessels near the surface of the skin. [7] The cause of the leaky capillaries is usually not known. [7]
Sarcoidosis is confused most commonly with neoplastic diseases, such as lymphoma, or with disorders characterized also by a mononuclear cell granulomatous inflammatory process, such as the mycobacterial and fungal disorders. [28] Chest radiograph changes are divided into four stages: [104] bihilar lymphadenopathy
When a substance other than air fills an area of the lung it increases that area's density. On both x-ray and CT, this appears more grey or hazy as opposed to the normally dark-appearing lungs. Although it can sometimes be seen in normal lungs, common pathologic causes include infections, interstitial lung disease, and pulmonary edema. [2] [3]
Complications are not common but include infection, lung abscess, and bronchopleural fistula (a fistula between the pleural space and the bronchial tree). [4] A bronchopleural fistula results when there is a communication between the laceration, a bronchiole, and the pleura; it can cause air to leak into the pleural space despite the placement of a chest tube.
