Four lifelong residents of the Republic of South Vietnam experienced chronic pulmonary dysfunction, hypereosinophilia. and a dramatic response to diethylcarbamazine therapy: the tropical eosinophilia syndrome. Chest roentgenograms of three of these men showed diffusely scattered, small, mottled areas of infiltration with apical sparing. None of these patients had detectable microfilaremia at the time of diagnosis, but one man had had Wuchereria bancrofti microfilaremia 1 year before. The evaluation of clinical or hematological abnormalities in persons who have resided in South Vietnam should include consideration of tropical eosinophilia.
