abstract: A 74 yr old woman from Gonabad, southern part of Khorasan Razavi Province of Iran was admitted to a Hospital of Gonabad, because of respiratory distress, exertional dyspnea and fever. Close contact with domestic animals, history of chronic obstructive pulmonary disease (COPD), and completely resolved pulmonary tuberculosis (TB) in remote past, were notable parts of her past medical history. Due to clinical, paraclinical and radiographic findings and because of recent hospitalization, she was admitted to internal medicine ward with the diagnosis of health care associated pneumonia (HCAP). Despite the application of broad-spectrum antibiotics and appropriate supportive care, she had a poor response to the treatment. During the daily visit in Intensive Care Unit (ICU), numerous white larvae were detected in both nostrils. Further investigation of oropharynx and tracheal tube aspiration, showed no more larvae in mentioned parts. An hour later, nasal spontaneous bleeding occurred. Otorhinolaryngology consultation was performed and led to surgical procedure. In ENT examination, there were numerous larvae and massive clot formation in both inferior meatuses and distal nasal septum perforation. Thirty-seven extracted larvae were transferred to Medical Entomology lab by vial 70% ethanol and 5 live larvae for rearing. After precise investigation by aid of light microscopy, the larvae were identified asChrysomya bezziana.Due to discovered 2ndlarvae stage and duration of hospitalization, this infestation was identified as nasal myiasis.
