Title:Intra-esophageal whitish mass - a challenging diagnosis
Version:2Date:27 April 2015
Reviewer: Amitabh Srivastava
Reviewer's report:
The authors present an interesting case of a calcified mass in the esophagus.
However, given the information provided it appears that this is most likely a
calcified mass in an esophageal diverticulum rather than a typical esophageal
fibrovascular polyp (FVP). Typical FVP are slender, finger like projections with a
narrow stalk that arise in a background of normal appearing esophagus. The sac
like diverticular distension seen on imaging in this case argues against the
diagnosis of FVP and suggests that stasis of contents was the most likely cause
of nodular calcification identified. Some of the more recent literature on giant FVP
and their overlap with atypical lipomatous tumor of the esophagus has also not
been discussed or cited in this manuscript. The lack of any histology images for
what is essentially a pathologic diagnosis is also a limitation of the submitted
work.
Level of interest: An article whose findings are important to those with closely
related research interests
Quality of written English: Needs some language corrections before being
published
Statistical review: No, the manuscript does not need to be seen by a statistician.
