Hymenolepiasis: an unusual cause of diarrhoea in Western Europe.

A young Indian man presented in England with a 6-month history of diarrhoea which started just before leaving India. He was found to have tropical enteropathy and H. nana infestation, but while the infestation and symptoms disappeared with antihelminthic treatment, the tropical enteropathy persisted. Hymenolepiasis is not well recognised as a cause of diarrhoea amongst Asians in Western Europe.
