Reviewer’s report
Title: 
Gastric lymphangioma: a case report and review of literature
Version: 
0 
Date: 
21 Apr 2022
Reviewer's report:
The authors presented an interesting and rare case. I have some comments as
follows:
1. The co-existence of gastric adenocarcinoma and lymphangionoma is rare. The
information of the synchronous gastric carcinoma should be provided.
2. Was the immunostain of D2-40 performed? As discussed in the manuscript, it
helps to confirm the diagnosis. 
3.The authors described the "the overlying squamous epithelium had no
malignancy". However, the squamous epithelium is absent in the normal antrum
mucosa. The histological image of the squamous epithelium overlying the tumor
should be supplemented.
