A human case of internal myiasis in Korea

A 71-year old male patient was admitted in Inha hospital due to right facial palsy, quadriplegia and aphasia. This patient was operated to replace his heart values 7 years ago and has been treated with Coumarin, an anti-coagulant drug, to prevent the formation of thrombus in the heart. A number of fly maggots continuously crawled out from the nasogastric tube set up for supplying a liquid diet and patient's mouth for 2 days until his death in the intensive care unit of hospital. These maggots were about 11.5 mm long on the average and identified as genus Lucilia belonging to family Calliphoridae. The lesion of this myiasis case might be regarded in the gastro-intestinal system of patient. This is the first report of an internal myiasis case in Korea.
