Two female white patients of 11 months and 1 year of age, respectively, with intestinal parasitism due to Inermicapsifer madagascariensis (Inermicapsifer cubensis) are presented. They were attended at the Pediatrics Outpatient Department of the "Pedro Kourí" Institute of Tropical Medicine during the last 3 years. Both patients who did not cure with the different treatment used against taeniasis and who used to expel parasites through the anus, were referred to this center, where they were diagnosed Inermicapsifer madagascariensis. Parasitism disappeared with a specific treatment with praziquantel.
