WITHDRAWN: A Rare Cause of Peri-esophageal Cystic Lesion.

Abstract

This article has been retracted: please see Elsevier policy on article withdrawal (https://www.elsevier.com/about/policies-and-standards/article-withdrawal). This article has been retracted at the request of the Editors-in-Chief. The article is a duplicate of a paper that has already been published in Natl Med J China, 第551例 吞咽困难—胸腔积液—后纵隔囊肿, Vol 101, No. 48, 3977-3980. Redundant publications overweigh the relative importance of published findings and distort the academic record of the authors. One of the conditions of submission of a paper for publication is therefore that authors declare explicitly that the paper has not been previously published and is not under consideration for publication elsewhere. As such, this article represents a misuse of the scientific publishing system. The Publisher reached out to the authors for an explanation, but they did not respond.
