• español

  Los autores reportan el caso de un adulto mexicano fallecido a conse­cuencia de una cardiopatía, en cuya autopsia se encontraron tres nódulos rojizos situados al nivel de la submucosa intestinal; al cortar uno de los nódulos se encontró en su interior una hembra adulta de Ancylostoma duodenale. Histológicamente los nódulos estaban formados por zonas hemorrágicas y áreas de reacción inflamatoria, conteniendo huevos y larvas de uncinarias.

  A case is reported of an adult Mexican male who died of heart disease, whose autopsy showed three readdish nodules situated at the level of the intes­tinal submucosa. In one of the nodules an adult female Ancylostoma duodenale was found. Histologically, the nodules were made up of hemorrhagic, zones and areas of inflammatory reaction containing eggs and larvre of uncinarire. The presence of eggs within the nodules suggests that hookworms survive there for some time, and points to the possibility of internal autoinfection, as is the case in Strongyloides stercoralis.
