We present herein the interesting case of a 43-year-old man in whom a rapidly growing polypoid tumor of the esophagus was histologically proven to be pseudosarcomatous carcinoma. Of particular interest was the unusual type of invasion displayed by this tumor, whereby the head of the polyp came into contact with and directly invaded the esophageal wall at the distal end of the pedicle to the submucosal layer, while invasion near the stalk was restricted to the mucosa. This style of invasion is considered to be caused by the mechanical pressure produced by the rapid growth of the tumor in the narrow esophageal lumen.
在此,我们报告一例43岁男性的有趣病例,其食管内快速生长的息肉样肿瘤经组织学证实为假肉瘤样癌。特别值得关注的是该肿瘤呈现出的异常浸润类型,即息肉头部在蒂的远端与食管壁接触并直接浸润至黏膜下层,而靠近蒂部的浸润仅局限于黏膜层。这种浸润方式被认为是由于肿瘤在狭窄的食管腔内快速生长产生的机械压力所致。
