Human fascioliasis (HF), caused by the common liver fluke Fasciola hepatica, is an endemic infection in many parts of tropical countries. HF can also be seen in some of the non-tropical countries. This report describes two girls with severe iron deficiency anemia and eosinophilia, who were diagnosed as HF. The infection was successfully eliminated with the administration of triclabendazole. No side effects or recurrence was observed after the treatment. It should be kept in mind that marked eosinophilia with severe iron deficiency anemia should alert pediatricians to the possibility of F. hepatica infection.
