Reviewer’s report
Title: 
A case of esophageal neuromuscular choristoma
Version:

Reviewer's report:
The authors have reported a very interesting case report. Neuro muscular
choristoma is a histopathological diagnosis which has not yet been reported in
the esophagus. However there are few issues the authors need to address. 
1. When EUS evaluation of the esophagus sub mucosal lesion was done; why
FNA/B was not taken ? If the biopsy report would have been a benign lesion;
then the sub mucosal resection and the subsequent perforation would have been
prevented. 
2. Discussion part: The authors must discuss the natural history of such a lesion.
What would have been the consequence if it would have been left alone ? Does
every sub mucosal esophageal lesion warrants removal/resection ?
3. English grammar and 
punctuation marks needs correction throughout the text.
