Core Tip

Core Tip: Malignant small round cell tumor (MSRCT) in the common bile duct has not been previously documented. Here we present the case of an MSRCT in the common bile duct. A 77-year-old female patient was admitted to hospital due to gastrointestinal hemorrhage and abdominal pain. We found a neoplasm in the common bile duct with active bleeding through a spyglass. We performed biopsy through the spyglass and placed a metal stent to stop bleeding. The pathological result suggested that it was an MSRCT metastasized from the back to the common bile duct.
