Liver abscess due to ascarid in Iran.

A deep 3-cm liver abscess with resulting exogenous cholecystitis, pericholecystitis and adhesions caused by an adult Ascaris was discovered by laparotomy in a 63-year-old man in northwest Iran. Though Ascaris infection rates are high in most major areas of the country, this apparently is the first case of liver abscess caused by Ascaris to be reported from Iran.
