Squamous cell carcinoma of the stomach is a rare, unusual lesion which tends to occur at a somewhat earlier age than adenocarcinoma. Grossly and radiologically the tumor is indistinguishable from adenocarcinoma and may involve any portion of the stomach. Although the pathogenesis of this lesion remains unclear, most authors favor the "metaplastic theory" for the development of the tumor. In this case it is felt that the tumor probably arose from gastric squamous mucosa present congenitally in the lesser curvature.
胃鳞状细胞癌是一种罕见的异常病变，其发病年龄往往比腺癌稍早。大体上和放射学上，该肿瘤与腺癌难以区分，可累及胃的任何部位。尽管这种病变的发病机制尚不清楚，但大多数作者支持肿瘤发生的“化生理论”。在本病例中，认为肿瘤可能起源于先天性存在于胃小弯处的胃鳞状黏膜。
