Adenosquamous carcinoma of the esophagogastric junction. Case report.

Adenosquamous carcinoma is a rare tumor with coexisting elements of infiltrating squamous cell carcinoma and adenocarcinoma. This tumor is reported to arise in different organs but rarely in the oesophagus. In most cases, it shows highly aggressive biological behaviour with high propensity to regional lymph-node metastasis and poor prognosis. We describe the management of a patient with an aggressive adenosquamous carcinoma of the esophagogastric junction.
