title: Eosinophilic lung disease in the tropics.
abstract: Paul Ehrlich first described the eosinophil in 1879. It is a pro-inflammatory cell that is involved in the immune defense against various offenders in atopic and nonatopic individuals. Eosinophils derive from an unknown progenitor cell in the bone marrow. This article reviews the etiology and effects of this condition.
