title: Liver adenosquamous carcinoma invading the esophagogastric junction - a case-report and a review of the literature.
abstract: A case of adenosquamous carcinoma of the liver involving the esophago-gastric junction is reported. The preoperative diagnosis of a submucosal tumor of the cardia of the stomach was made following a barium meal study, gastrofiberscopy, ultrasonography, and computed tomography. At surgery, a tumor was found measuring 6x5 cm in diameter and involving the left lobe of the liver, lower esophagus and cardia of the stomach, and the origin of the tumor was unclear. Post-operative histopathology revealed that the tumor contained two different malignant components of glandular and squamous cells. An adenosquamous carcinoma originating in the liver was suspected, since the cancer cells did not involve the esophago-gastric mucosa and were mainly located in the S2 of the liver. Despite aggressive adjuvant chemotherapy, the patient died of a recurrence in the liver seven months later. This seems to be the first documentation of adenosquamous carcinoma of the liver invading the esophago-gastric junction.
