Abstract:
Churg-Strauss syndrome (CSS) is characterized by hypereosinophilia and a systemic necrotizing vasculitis seen almost exclusively in patients with asthma. The most common pathological findings in the chest in CSS are eosinophilic pneumonia, necrotizing vasculitis and granulomatous inflammation (extravascular granuloma). However, tracheobronchial mucosal lesions have rarely been reported in CSS. The authors report two patients with CSS who had multiple tracheobronchial mucosal lesions that were found by fibreoptic bronchoscopy. They were tiny nodular lesions and necrotizing bronchial inflammation with many eosinophils was observed upon pathological examination. The authors concluded that tracheobronchial mucosal lesions may be one of the manifestations of vasculitis seen in CSS.

Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
