Nosocomial nasal myiasis in an intubated patient.

We report a case of nasal myiasis caused by Sarcophaga spp., noted during hospitalization. A 74-year-old man was admitted with non-ST-elevation myocardial infarction. The patient underwent coronary arterial bypass surgery and was then mechanically ventilated by means of a nasotracheal tube for the next 8 days. After extubation, a total of seven maggots were retrieved from both nostrils. The larvae were removed and reared to mature flies, which were identified as Sarcophaga peregrina. From the clinical course and the fly's life cycle, it was concluded that the infestation was hospital-acquired.
