Abstract

<p>A 72-year-old man who had the chief complaint of asitia was referred to our institution for further investigation of the bile duct tumor. US revealed low echoic mass at the inferior common bile duct (CBD). CT revealed the wall thickening at the inferior CBD which showed delayed enhance. On MRI, the wall thickening was visualized as a hypointensity on T2-weighted image. Subtotal stomach-preserving pancreaticoduodenectomy was performed and resected specimens showed > 50% of the tumor contained extracellular mucin and adenocarcinoma cells floated in mucin pools. Signet ring cells were found in a part of tumor. The final diagnosis was mucinous carcinoma of inferior CBD. Generally, it is thought that proliferating potential of mucinous carcinoma is low. However, careful follow-up is necessary because the tumor contained signet ring cells in this case.</p>
