© 2017 by The American Society of Tropical Medicine and Hygiene. Finding Dicrocoelium dendriticum eggs in human feces is exceptional and there are few prevalence data available. True infection occurs after accidental ingestion of ants containing metacercariae and spurious infection through the consumption of infected animal liver. Differential diagnosis between true and pseudo-infections is performed through stool examination after a diet free of liver. In addition, microscopy can help to differentiate the type of infection. We report six cases, all from sub-Saharan Africa, detection of this fluke at the Tropical Medicine Unit Vall d'Hebron-Drassanes (Barcelona, Spain). Dicrocoelium dendriticum transit eggs were visualized in five cases and there were no subsequent visualizations after diet, which reinforces that all these cases were false parasitism. In one case, few embryonated eggs were observed and the patient was treated for a possible true parasitism. There is a need to investigate the prevalence of D. dendriticum in our country focusing on the distinction between true and spurious infections.
