Unusual foreign body aspiration as a cause of asphyxia in adults: an autopsy case report.

Most asphyxia deaths caused by foreign body aspiration occur in children and the elderly. It can also occur in specific high-risk groups of adults, such as those with underlying esophageal diseases, prisoners, those with mental retardation, and those with psychiatric illnesses. We report the case of a 49-year-old man, without previous medical history, who died rapidly after aspirating a sole fish while he was unraveling the fishing net using his teeth. At autopsy, the foreign body was found in the trachea, wedged in the carina and obstructing the right bronchus origin. The finding from the usual toxicological screening was negative.
