Introduction:
Chlorosilane is widely used in modern industry. The health effect in humans after chlorosilane exposure is still unclear.
Case Summary:
A 57-year-old male developed severe lung damage after accidental inhalation of chlorosilane. He received mechanical ventilation and experienced refractory CO2 retention with difficulty weaning. Bronchoscopy showed diffuse endobronchial polyposis two months after exposure.
Images:
Serial radiographs, bronchoscopy images demonstrated the course of severe respiratory injury and an uncommon sequalae of diffuse inflammatory endobronchial polyps.
Discussion:
The pathogenesis of polyp formation may be associated with prolonged inflammation. Interventional bronchoscopy was used to remove the polyps. Corticosteroids may be considered, but there is the risk of superimposed infection.
Conclusion:
Chlorosilane inhalation could induce severe lung damage. Multiple endobronchial polyps may be a severe sequela contributing to difficulty weaning.

Chronic Obstructive Pulmonary Disease-I: Introduction
Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

COPD: Pathogenesis and Clinical Features
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...
