Endobronchial obstruction in connective tissue diseases: an uncommon but life threatening complication: two case reports

Abstract

Background: Granulomatosis with polyangiitis and relapsing polychondritis are rare, multisystemic and potentially life-threatening connective tissue diseases. We present two cases of severe endobronchial obstruction in the aforementioned conditions and discuss difficulties with detection and treatment. Despite differing underlying pathophysiologies, endobronchial disease is a less frequently reported but serious complication of both conditions. Case presentation: Case 1, a 31-year-old South Asian woman with relapsing polychondritis, required partial tracheal resection and reconstruction in combination with immunosuppressive therapy to achieve respiratory recovery following collapse of her ri..
