Lipoid pneumonia is a rare form of pneumonia. There are two types; exogenous and endogenous. The exogenous form often occurs due to accidental aspiration of fatty substances (such as; animal, vege- table or mineral fats). For elderly patients inparticular, the most common causes are oily nose drops and the use of oily substances for laxatives, such as castor oil. They are compounds containing hydrocarbons and hydrogen. The most common example is the oil found in paraffin, olefins, aromatics and the the acet- ylene series. Aspiration of high viscosity petroleum hydrocarbons may cause lipoid pneumonia. The accidental aspiration of hydrocarbon compounds can also cause acute illnesses such as fire eaters' pneu- monia. In particular, the storing of hydrocarbon compounds in inappropriate packaging in the home, such as water, fruit juice or carbonated beverage bottles, are important factors facilitating the acci- dental drinking of these compounds by children. Since it does not have any specific clinic and radio- logical finding, it may be difficult to diagnose it, un- less there is strong suspicion, or data is derived from anamnesis. Though a more common form of serious poisoning in childhood, in this study we, present two cases of lipoid pneumonia, diagnosed in adults.
