Polypoid epithelial malignancies of the esophagus are rare tumors. One hundred fifty cases of epithelial malignancy of the esophagus accessioned to the Registry of Radiologic Pathology at the Armed Forces Institute of Pathology were reviewed with respect to morphologic and pathologic characteristics. Only large intraluminal polypoid epithelial masses were analyzed. Criteria used to select cases were: (1) size greater than 4 cm, (2) expansion of the esophageal lumen by the bulky tumor, and (3) absence of constriction or wall infiltration. Twenty-two lesions met these criteria (15 spindle cell carcinomas, two carcinosarcomas, three squamous cell carcinomas, and two oat cell carcinomas). When an esophageal neoplasm is polypoid and bulky, creates a "cupola" effect, has scalloped edges, expands the lumen of the esophagus, and is pedunculated, one must consider spindle cell carcinoma as the primary diagnosis.
食管息肉样上皮恶性肿瘤是罕见的肿瘤。对武装部队病理研究所放射病理登记处收录的150例食管上皮恶性肿瘤病例的形态学和病理学特征进行了回顾。仅分析了腔内大的息肉样上皮肿块。选择病例的标准为：（1）大小大于4厘米，（2）巨大肿瘤使食管腔扩张，（3）无狭窄或管壁浸润。22个病变符合这些标准（15例梭形细胞癌、2例癌肉瘤、3例鳞状细胞癌和2例燕麦细胞癌）。当食管肿瘤为息肉样且巨大，产生“圆顶”效应，边缘呈扇形，使食管腔扩张且有蒂时，必须将梭形细胞癌作为主要诊断考虑。
