We report a case of chronic urticaria associated with <em>E. nana</em> in a 34-year-old Italian woman. The patient suffered from abdominal pain, diarrhoea and weight loss. The disease appeared after a trip to Vietnam. Laboratory examinations showed mild blood eosinophilia. Three coproparasitological examinations were positive for cysts of <em>E. nana</em>. The patient was successfully treated with two courses of metronidazole (2 g/day for 10 days each). No antihistamines were used. Three coproparasitological examinations, carried out at the end of the therapy, were negative. Follow up (six months) was negative. <em>E. nana</em> can be responsible for very rare cases of abdominal pain, diarrhoea, polyarthritis and urticaria.</p> ER -
