Title: Esophageal lymphangioma: a case report and review of literature  
 
Version: 0 Date: 11 Jun 2019  
 
Reviewer: Andrzej Wincewicz  
 
Reviewer's report:  
 
The authors reported an interesting case of esophageal lymphangioma in BMGE -D-19-00337. 
The presented photographic documentation is sufficient and ancillary techniques like appliance 
of D40 stain is a golden standard in presentation of this kind of lesions. An identification of 
1,5cm wide esophageal submucosal mass could be a matter of great concern. The presented 
clinical and radiolog ical and endoscopic procedures follow the standard pattern of management 
of such an lesion.  
 
The review of literature is clear and concise in the discussion section and provides a 
straightforward insight in epidemiology of the tumor. The microscopic descrip tion is done well 
in discussion section but I would consider it more suitable in case description part, which also 
contains well done histopathological report. Thus it is a kind of repetition of writing of 
microscopic appearance in both in case description  and discussion section.  
 
However the paper is written in good English and it is a pleasure to read such a well done case 
report for not only didactic professional merits.  
 
With compliments,
