Conglomerate masses can also develop in sarcoidosis, [5] but usually near the hilae and with surrounding paracicatricial emphysema. The disease arises firstly through the deposition of silica or coal dust (or other dust) within the lung , and then through the body's immunological reactions to the dust.
Pulmonary function: increased residual volume, increased total lung capacity, fixed obstruction, low diffusing capacity of the lung for carbon monoxide that corrects with alveolar volume; High-resolution CT scan: diffuse pulmonary nodules 4–10 mm, greater than 20 nodules, mosaic attenuation or air trapping in greater than 50% of the lung
The most common cause of a single lung cavity is lung cancer. [4] Bacterial, mycobacterial, and fungal infections are common causes of lung cavities. [5] Globally, tuberculosis is likely the most common infectious cause of lung cavities. [6] Less commonly, parasitic infections can cause cavities. [5] Viral infections almost never cause cavities ...

The new paradigm recognizes that lung cancers are a large and extremely heterogeneous family of malignant neoplasms, [2] with over 50 different histological variants included in the 4th (2004) revision of the World Health Organization typing system, the most widely used lung cancer classification scheme ("WHO-2004").

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. [2]
[citation needed] Treatment of diseases which increase the risk of aspergilloma, such as tuberculosis, may help to prevent their formation. In cases complicated by severe hemoptysis or other associated conditions such as pleural empyema or pneumothorax , surgery may be required to remove the aspergilloma and the surrounding lung tissue by doing ...
The Pancoast tumor was first described by Hare in 1838 as a "tumor involving certain nerves". [2] It was not until 1924 that the tumor was described in further detail, when Henry Pancoast, a radiologist from Philadelphia, published an article in which he reported and studied many cases of apical chest tumors that all shared the same radiographic findings and associated clinical symptoms, such ...
