title: Anatomo-clinical and molecular description of liver neotropical echinococcosis caused by Echinococcus oligarthrus in human host.
abstract: Since humans rarely play the role as Echinococcus oligarthrus host, there is lack of knowledge about the complex infectious process. Only three cases have been reported to occur in humans in the neotropics until now. We present the anatomo-clinical and molecular findings describing a new case of infection by E. oligarthrus in a man. The muscular or subcutaneous tissues tropism described for this species in the previously reported cases was not present, but a liver tropism was observed. Additionally, the larval stage rostellar hooks morphometry differed from E. oligarthrus in the other human cases.
