Human intestinal myiasis caused by Eristalis tenax.

INTRODUCTION

Human intestinal myiasis is an uncommon parasitic infection, usually related to the accidental ingestion of Eristalis tenax eggs.

METHODS

We report the case of a 47-year-old woman who presented with passage of motile larvae in stool. Diagnosis was established by macroscopic examination of the faecal sample.

RESULTS

Larvae compatible with E. tenax, a fly with worldwide distribution, were identified. Treatment with ivermectin was initiated, with favourable clinical outcome.

CONCLUSIONS

This case highlights the importance of food hygiene and the need to consider parasitological examination in patients with nonspecific digestive symptoms and unusual stool findings.
