Sarcomatoid carcinoma of the common bile duct presenting as painless jaundice

A woman in her 70s presented with painless jaundice and index biopsy of a common bile duct (CBD) mass obtained by endoscopic retrograde cholangiopancreatography was suspicious for malignant peripheral nerve sheath tumour. Treatment consisted of pancreaticoduodenectomy, and final pathology results were consistent with sarcomatoid carcinoma. Postoperative complications included pancreaticojejunal leak, surgical wound infection, bacteraemia, myocardial injury, and significant ulceration and stricturing of the oesophagus. 14 weeks post-pancreaticoduodenectomy, the patient was found to have a perforated viscus, gastroduodenal leak and diffuse small bowel ischaemia-the patient passed away following emergent laparotomy. We aim to add to the limited literature surrounding this rare CBD neoplasm.
