    A 58-year-old woman with no prior medical history, presented with a 5-month history of productive cough, worsening breathlessness and weight loss of 5 kg despite three courses of oral antibiotic therapy. On examination she was afebrile, there was reduced air entry in the right lung base to auscultation and oxygen saturations on room air were 86%. Serum C reactive protein was elevated at 26.2 mg/L (range 0–5 mg/L) and white cell count was 9.6×109/L (3.5–11×109/L), and evidence of eosinophilia was 1.7×109/L (0–0.5×109/L). Chest radiograph showed complete collapse of the right middle and lower lobes and bronchial cut-off sign of the right main bronchus (figure 1A). CT of the chest demonstrated a large endobronchial obstructing lesion in the right main bronchus highly suspicious for an endobronchial tumour (figure 1B,C)
