Pneumoconiosis is an occupational lung disease and a restrictive lung disease caused by the inhalation of dust. In this case, the fine dust silica, emitted from volcanoes, is the cause.



Depending on the type of dust, variants of the disease are considered.

Types include:

In addition, it has been speculated that astronauts subject to prolonged exposure to lunar dust may be susceptible to a type of pneumoconiosis. No cases exist yet, but future Moon missions are expected to take precautions against such exposure.

Positive indications on patient assessment:

  • Shortness of breath
  • Chest X-ray may show a characteristic patchy, subpleural, bibasilar interstitial infiltrates or small cystic radiolucencies called honeycombing

Pneumoconiosis in combination with multiple pulmonary rheumatoid nodules in rheumatoid arthritis patients is known as Caplan's syndrome.[1]

Simple English

Pneumoconiosis is a form of "lung disease". It is not a disease. Lung diseases are progressive degenerative disorders. (NB: They are not diseases). Lung diseases are caused by air pollution in the form of particulates.

Pneumonoultramicroscopicsilicovolcanoconiosis is a lung disease caused by the breathing-in of very small particles of sand or quartz dust found in volcanoes.

The origins of this forty-five-letter word have, however, been considered as a hoax. It was first seen in the Oxford English Dictionary in 1936.

The real name of this disease is the fourteen-letter pneumoconiosis. This is the longest word in English (other than names of places).

There is another long word and it is 30 letters it is "Pseudopseudohypoparathyroidism," and is a certain kind of disorder.
