ABSTRACT
Pulmonary eosinophilia is considered when there are respiratory symptoms with pulmonary infiltrates and peripheral and/or pulmonary eosinophilia 1 . Although parasitic infestations are common in tropical countries, a detailed clinical evaluation and follow up is necessary to rule out alternate aetiologies, including an underlying hypereosinophilic syndrome. The easiest tool for identifying eosinophilia is a simple estimation of the absolute eosinophil count. This is obtained by multiplying the percentage of eosinophils in the differential count with the total leucocyte count. Management is based on the clinical severity, evidence of end organ involvement and possibility of a neoplasm. In this review, I have attempted a structured approach to its identification and treatment as per recent evidence.
