Reviewer’s report
Title: 
Solitary Rectal Ulcer Transformation to Cap Polyposis in a 15-Year-Old
Child; A Case Report
Version: 
2 
Date: 
17 Dec 2021
Reviewer's report:
The paper reports a rare case of cap polyposis, a very rare disease in which a
correct diagnosis is essential to avoid unnecessary harmful treatments. The paper
does not add new informations about the disease, but its interest is related to the
paucity of reported cases. The discussion should be more focused on the etiology
of the disease, and to the possible relationship between solitary rectal ulcer and
cap polyposis, and the references should be improved on this aspect.
