This report aims to present a case of pharyngeal myiasis caused by the larvae of Oestrus ovis (Diptera: Oestridae). A 55-yr old drug addict living in the Shahindeje village of Western Azerbaijan Province, northwestern Iran was referred to the Emam Reza Hospi­tal in Tabriz, having a medical history of Chronic Obstructive Pulmonary Disease (COPD) and hospitalized due to respiratory distress, 20 days ago. He was intubated with a mechanical ventilator (MV) because of his respiratory distress condition. There was an evidence of the presence of pulmonary nodules in his lungs following diagnosis, and a CT scan revealed a cavity in his lung. During the nasogastric intubation procedure, a larva was seen emerging from the patient’s mouth by one of the staff of the intensive care unit of the hospital. A laboratory diagnosis was per­formed in the Entomology Department of the School of Medicine, Tabriz University of Medical Sciences. Interest­ingly, larvae of O. ovis were identified and confirmed following the laboratory proceedings. https://jad.tums.ac.ir/index.php/jad/article/view/603 https://jad.tums.ac.ir/index.php/jad/article/download/603/344
