title: [Primary adenosquamous carcinoma of the liver: a case report].
abstract: Primary adenosquamous cell carcinoma of the liver, a variant of cholangiocarcinoma is very rare disease and its prognosis is known to be very poor. We describe here a case of primary adenosquamous carcinoma of the liver. The patient was a 60-year-old woman who complained of an eight-month history of intermittent upper abdominal pain. Abdominal computed tomography scan revealed a low density mass and intrahepatic duct stones within the dilated left intrahepatic duct in the left lateral segment. Needle biopsy of the mass was done and the histologic diagnosis was cholangiocarcinoma. Left lobectomy was then performed. Upon gross examination, there was a well defined solid mass and intrahepatic duct stone in the dilated bile duct. Microscopically, the tumor was composed of both adenocarcinoma and squamous cell carcinoma.
