胃原发性鳞状细胞癌和腺鳞细胞癌

PRIMARY SQUAMOUS AND ADENOSQUAMOUS CARCINOMA OF STOMACH

对４例原发性胃鳞状细胞癌和腺鳞癌进行临床病理分析，并结合文献对其诊断、尤其组织学起源进行讨论。结果１例胃鳞状细胞癌（胃镜活检材料），另３例胃腺鳞癌有明显的鳞癌与腺癌过渡现象。４例均在诊断后７个月之内死亡。认为对胃鳞状细胞癌，应再次尽可能多取材、多制片以明确是单纯胃鳞状细胞癌或胃腺鳞癌。胃腺鳞癌起源倾向腺癌的鳞状化生，建议病理报告注明鳞癌与腺癌成分各占的比例。

A clinicopathological analysis was conducted in 4 cases with primary squamous cell (SCC) and adenoqsuamous cell carcinoma (ASC) of stomach.3 were of adenosquamons cells.However the other was diagnosed as simple squamous cell carcinoma,while the likelihood of ASC could not be ruled out becanse the diagnosis was established with endoscopic biopsies rather than resected specimens.The transitional features of adenosqnamous to squamous cells were detected.Hence when gastric SCC is doubted as many biopsies and sections as possible should be done to define whether it is simple SCC or ASC.In additon it is suggested that when ASC be assured the proportions of adenomatus and squamous cell components should be indicated.
