Resumen
Intestinal parasites are among the most common pathogens found in humans and
Ascaris lumbricoides, the etiological agent of ascariasis, is one of the enteroparasites
that has high worldwide prevalence. Ascaris lumbricoides is transmitted by the fecaloral route and its occurrence is associated to poor sanitary conditions. Typically, the
disease is asymptomatic and the severity is related to parasite load. The small
intestine of man is the natural habitat of Ascaris, but under adverse conditions such
as hiperparasitism or when any irritating factor acts on the worm, it can reach
locations as liver, pancreas, gallbladder, lungs, ears, nostrils, urethra and other.
Complications that may arise from the ectopic migration are serious and can cause
death of the individual. Routine diagnosis of ascariasis is done through fecal
examinations for detection of eggs, but in cases ectopic migration, imaging tests
allow the identification and set the amount and anatomical position of the parasites.
The treatment involves the administration of anthelmintics, associated to surgery or
endoscopy for extraction off the "erratic ascaris". A description of cases of ectopic
ascariasis, as well as a review about this disease, are reported in this work.
