Sources of such<unk> s could be either exogenous or endogenous. Exogenous: from outside the body. For example, inhaled nose drops with an oil base, or accidental inhalation of cosmetic oil. Amiodarone is an anti-arrythmic known to cause this condition. Oil pulling has also been shown to be a cause. Fire breather's pneumonia from the inhalation of hydrocarbon fuel is a specific variant. At risk populations include the elderly, developmentally delayed or persons with gastroesophageal reflux. Switching to water-soluble alternatives may be helpful in some situations. Endogenous: from the body itself, for example, when an airway is obstructed, it is often the case that distal to the obstruction,<unk> -laden macrophages and giant cells fill the lumen of the disconnected airspace.
