View detailsIdiopathic pulmonary fibrosis
Idiopathic pulmonary fibrosis is a disease of unknown etiology characterized by diffuse alveolitis and alveolar structural disorganization, ultimately leading to pulmonary interstitial fibrosis. This disease is common in elderly individuals over 50 years old, with progressive dyspnea and cough as the main symptoms.
Chronic eosinophilic pneumonia
Chronic eosinophilic pneumonia, also known as prolonged pulmonary eosinophilic infiltration, or chronic granulocytic pneumonia, is a group of lung diseases characterized by an increase in eosinophils in the blood or tissues. The majority of cases of this disease occur in Caucasians, predominantly affecting women, with a high incidence between 30 and 40 years of age. The etiology of this disease is unknown, and the main symptoms include cough, fever, night sweats, weight loss, and fatigue.

Silicosis, also known as silicosis, is the most common type of pneumoconiosis. It is a disease primarily characterized by widespread nodular fibrosis of the lungs, caused by long-term inhalation of large amounts of silicon dioxide dust. Common symptoms of this disease include cough, sputum production, hemoptysis, chest pain, and dyspnea.
