Tropical pulmonary eosinophilia. Report of a case.

Tropical pulmonary eosinophilia (TPE) is an unusual manifestation of filarial infection, most commonly found in South-East Asia and caused by immunologic hyperresponsiveness to Wuchereria bancrofti and Brugia malayi. This report concerns a case of TPE in a 25-year-old Indian male who had been living in Italy for two years and was admitted to hospital with chest pain. Diethylcarbamazine therapy proved effective in rapidly eliminating symptoms and pulmonary abnormalities, as well as normalizing of laboratory findings.
