Biliary obstruction caused by plant seeds

Abstract

Biliary obstruction is rarely caused by foreign objects; therefore, the precise diagnosis may be challenging. Even in rare situations, cases of biliary obstruction caused by plant seeds have not been reported previously. To our knowledge, herein, we report the first case of biliary obstruction caused by accumulated plant seeds forming a solid mass with inflammatory cells and bile juice, which were identified as Solanum lycopersicum, Brassica, and Citrus species by DNA analysis and pathological assessment of the specimen after surgical resection for biliary obstruction suggestive of cholangiocarcinoma.
