- Is it Possible to Cough Up a Stone?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: I couldn't believe it but apparently it's true. My husband had a
- severe coughing spell and produced, instead of mucus, a little pebble. Is it
- possible to cough up a stone? Where would it come from?
-

- ANSWER: Lithoptysis, or the spitting up of stones, has been documented since
- ancient times and is the result of broncholithiasis, a disorder where
- calcified material enters the tracheobronchial tree. Its often linked to lung
- infections, such as tuberculosis, since the gravel-like stones, or
- broncholiths, are believed to form when lymph nodes that surround the bronchi
- (tubes that carry the oxygen to the lung tissue) become saturated with calcium
- and calcify during the inflammatory stages of such an infection.
- Though the exact biochemistry of tissue calcification is not completely
- clear, we do know that once a lung infection develops, the necrotic or dead
- tissue in the lung and surrounding lymph nodes become alkaline during the
- healing process. This alkaline environment allows calcium phosphate and
- carbonate to mass together and form deposits. Then, due to the constant
- motion of the cardiopulmonary system, these calcified deposits enter the
- bronchial tree by erosion and the stone is formed.
- In many cases of broncholithiasis, no treatment is necessary because once
- the stone is coughed up, the lung can usually clear itself. However,
- broad-spectrum antibiotics may be prescribed for patients who are prone to
- lung infections, and routine follow-ups should always be made to check for any
- possible complications. I hope you have kept the "pebble" to show to your
- physician, and will now seek the necessary professional care.
