CASE PRESENTATION: A 46-year-old woman with Behcet’s disease complicated by recurrent thrombotic events presented with left-sided pleuritic chest pain, cough, and dyspnea after aspirating a calcium citrate tablet that morning. On exam, she had normal oxygen saturation and non-labored breathing, but diminished left-sided breath sounds. Chest radiograph revealed a 1.8 cm oval density in the left mainstem bronchus with associated atelectasis. She underwent urgent bronchoscopy revealing inflamed mucosa of the proximal left mainstem bronchus and minute remnants of the calcium tablet. Endobronchial biopsies were obtained to confirm benign inflammation. The patient was discharged home the following day. She re-presented six days later with hemoptysis. Vital signs and exam were unremarkable. Chest CT with contrast was significant for a left mainstem bronchus soft tissue density, but no broncho-arterial fistulae. Repeat bronchoscopy revealed extensive granulation tissue with blood adherent to the medial wall of the proximal left mainstem bronchus. The airway was nearly completely obstructed, thus requiring debridement. Argon plasma coagulation was applied to the severely inflamed mucosa to prevent further granulation tissue formation and hemoptysis. Given the rapid recurrence, she was empirically started on fluticasone. She was seen in clinic three weeks later and had returned to her clinical baseline.
