Nguyen Van De,1 Duyet Le Van2 1Department of Parasitology, Hanoi Medical University of Vietnam, 2Clinical Laboratories, National Hospital of Tropical Diseases, Hanoi, Vietnam Abstract: In 2013, two cases of infection by Echinococcus that caused cystic echinococcosis in the lungs were reported. In the first case, there was a cyst of 6 x 7 cm in diameter, and in the second case, there were four cysts of 5 x 6 cm, 4 x 4 cm, 3.5 x3 cm and 2.5 x 2 cm in diameter, respectively. In both cases, Echinococcus larvae were collected from the cysts. The larvae were identified as Echinococcus ortleppi by morphology and a molecular method (using reduced nicotinamide adenine dinucleotide hydrogenase [NADH] with 99%–100% homology compared with E. ortleppi in GenBank). This is the first time that this species has been found in humans in Vietnam. Keywords: E. ortleppi, hydatid, Vietnam
