食管腺鳞癌:是一种罕见的唾液腺肿瘤。可能发生于食管粘液腺,很易与粘液表皮样癌混淆。腺鳞癌组织中具有腺癌和鳞癌两种浸润成份,但并不紧密相混;而粘液表皮样癌系鳞癌的癌巢中存在粘液分泌细胞。腺鳞癌主要发生在胃,但可以就近扩展到下段食管。当腺癌组织中出现成熟的鳞状上皮时,便称为腺棘皮癌。食管原发性绒毛膜腺癌是一种极为罕见的癌。它可能是一种腺癌成分的变异巨细胞。它能分泌绒毛膜促性腺激素。燕麦细胞癌:食管燕麦细胞癌属于少见的癌,英
Esophageal adenosquamous carcinoma: is a rare salivary gland tumour. May occur in the esophageal mucous glands, it is easy to be confused with mucoepidermoid carcinoma. Adenocarcinoma and squamous cell carcinoma have two types of invasive components in adenosquamous carcinoma, but they are not closely mixed. Mucus-secreting cells are present in the carcinoma nest of mucoepidermoid carcinoma. Adenosquamous carcinoma occurs mainly in the stomach, but can be extended to the lower esophagus. When mature squamous epithelium appears in adenocarcinoma, it is called adenocarcinoma. Esophageal primary choriocarcinoma is an extremely rare cancer. It may be a variant giant cell of the adenocarcinoma component. It secretes chorionic gonadotropin. Oat cell carcinoma: Esophageal oat cell carcinoma is a rare cancer, English
