The Editor,

Sir,

We describe a case of tracheal amyloidosis admitted with rectus abdominis muscle haematoma due to severe coughing. He was 53 years old and he had a history of uncontrolled asthma. Respiratory system examination was normal. There was a swelling on the right abdominal wall. There was an enlargement of the superior mediastinum, narrowing of the trachea and pleural thickening of the left hemithorax on chest X-ray. There were bilateral miliary nodules, calcified lymph nodes, pleural thickening and localized thickness in the middle  part of the right tracheal wall on computed tomography of the thorax CT (Fig 1a-b).
