A granulomatous liver abscess which developed after a toothpick penetrated the gastrointestinal tract: report of a case

Abstract

An unusual case of a toothpick perforating the stomach, then penetrating the liver, and thereafter forming a liver abscess is reported. A 48-year-old woman who had ingested a toothpick 1 month earlier was admitted to our hospital because of severe epigastralgia which had progressively worsened. A laparotomy was performed because a granulomatous abscess in the liver due to this ingested foreign body was suspected. We found a granulomatous abscess in the liver due to the penetration of the toothpick through the stomach. The toothpick had become completely embedded about 2 cm deep in the left lobe of the liver. When dissecting the tumor, a 5.5-cm toothpick was removed, and a partial lateral resection of the liver was performed. The histological diagnosis was a hepatic abscess with granulomatous change. This was a rare case of a migration of an ingested toothpick into the liver through the stomach.
