neglected human fascioliasis case in a visceral leishmaniasis endemic area, north-western iran

ardabil province, northwestern iran, is endemic for visceral leishmaniasis of mediterranean type from many years ago. this situation might cause to underestimate other important diseases, which occur spo­radically within the same area. in this case, a 6-year-old male patient in this area was treated as in­fected with visceral leishmaniasis initially with seropositive result for visceral leishmaniasis. after­wards, histo­pathological study of crashed material and tissue sections surprisingly revealed numer­ous liver fascio­lid fluke eggs. this case demonstrates that in an area endemic for a given parasito­ses, other im­portant infectious diseases must be considered as well.
