Eosinophilic Pleural Effusion: A Rare Manifestation of Hypereosinophilic Syndrome

Abstract

Several cases of eosinophilic pleural effusions have been described with malignancy being the commonest cause.
Hypereosinophilic syndrome is a rare disease and very few cases have been reported of HES presenting as
eosinophilic pleural effusion. We report a case of 36 year old male who presented with dry cough and shortness of
breath. He had bilateral pleural effusion with marked peripheral eosinophilia. This patient represents a very
unusual presentation of HES with bilateral pleural effusion.
