Description
Sachiko Ishikami and co-authors present a 2026 case report on a liver tumor that held two cancer types inside one mass. The cancer, arising in the bile ducts within the liver, comes in small-duct and large-duct forms. A rare benign growth linked to the large-duct form was also present.
The patient was a 75-year-old man with no symptoms. A 35-millimeter mass turned up during checks for prostate cancer. Surgeons removed part of the liver, and lab study found both cancer types side by side in the single lesion. Such mixed cases are exceedingly rare, the authors note. Documenting them sharpens how pathologists read tumors that refuse to fit one label.
