Abstract
Myiasis is a pathology caused by the infestation of fly larvae species which affects vertebrates’ tissues or organs including humans. It can be classified entomologically or according to tissue tropism. Intestinal myiasis is rare and difficult to diagnose given its non-specific symptoms; the only way to confirm a case is by identifying the expelled larvae. This is the first case of intestinal myiasis reported in the department of Nariño (Colombia) in a 6-year-old child from a low-income family in the urban area of the municipality of Policarpa where there is no adequate treatment and no disposition of wastewater and basic sanitation conditions are insufficient. The clinical case was related to chronic diarrhea, abdominal pain, and anal pruritus with the subsequent expulsion of a larva identified by its morphological characteristics as Eristalis tenax fly larva.
