Tropical parasitic lung diseases.

Though parasitic lung diseases are frequently seen in tropical countries, these are being increasingly reported from many parts of the world due to globalisation and travel across the continents. In addition, the emergence of human immunodeficiency virus (HIV) infection/acquired immunodeficiency syndrome (AIDS), the frequent use of immunosuppressive drugs in many diseases and the increasing numbers of organ transplantations have resulted in a renewed interest in many tropical parasitic lung diseases. This review outlines the recent developments in the pathogenesis, diagnosis and management of common and rare parasitic lung diseases.
