Primary Gastric Adenosquamous Carcinoma: A Case Report.

Gastric adenosquamous carcinoma (GASC) is a rare variant of gastric cancer; the limited data available suggest that these tumors are more aggressive and have a worse outcome in comparison to gastric adenocarcinoma. Currently, the management of GASC is similar to adenocarcinoma. We report a case of GASC that progressed rapidly despite treatment.
