Erst von Romberg was the first one to describe, in 1891, the pulmonary arterial hypertension (PAH), as a "pulmonary vascular sclerosis". Since than, several groups and sub-groups of the condition were defined, mostly based on clinical features. The latest classification was established in 2013 in Nice, France (Simonneau et al., 2013). ...

Endobronchial involvement is a relatively uncommon but well-described presentation in Granulomatosis with polyangiitis (GPA). Self-expandable metallic stents (SEMs) should be reserved for the malignant airway disorder to maintain airway patency, but have been used for benign disease in specific cases. We present a case of longstanding endobronchial GPA with recurrent ...
