胃肠道原发的鳞状上皮细胞癌可分为单纯型、即鳞状上皮细胞癌(squamous cell carcinoma)和混合型、即腺棘皮细胞癌或腺鳞癌(Adenoacanthoma or Adenosquamous carcinoma),除见于贲门以上及肛管以下外,其余部位均较少见,发生于胃内者更属罕见。本院近两年收治胃窦部鳞癌和腺鳞癌各1例,迥盲部腺鳞癌1例,现就其病理起源与临床意义略加讨论,供临床参考。 Primary squamous cell carcinoma of the gastrointestinal tract can be divided into simple type, namely squamous cell carcinoma and mixed type, ie adenoacanthoma or Adenosquamous carcinoma. Outside the fontanel and below the anal canal, the rest are rare, and those occurring in the stomach are even rarer. In the past two years, this hospital has treated 1 case of squamous cell carcinoma and 1 case of adenosquamous carcinoma of the gastric antrum, and 1 case of adenosquamous carcinoma of the orbital blind. We have discussed the pathological origin and clinical significance of this case for clinical reference.
