Reviewer's report:
This report of a rare and probably overlooked disorder is clear and well-written.
Some minor revisions are required as follows:
There are some spelling mistakes and some abbreviations need to be explained
the first time they are used in the text
line 39: EBRV marker
Line 48: the abbreviation IM for infectious mononucleosis is used for the first
time in the paper and it should be explained
Line 92 Formulation of multiple ulcers: spelling mistake; Line 93 lymphocytes
infiltration in the plasma: the meaning is not clear
Line 94 atypical lymphocyte: it should be plural. Line 108 the most common
extra involving site of LPD: there is a grammatical error
Line 149 Those ulcers lack of typical features of CD or TB: the abbreviations
should always be explained the first time they are used in the text
Line 153 similar to CD and ITB. Is it ITB or TB? The abbreviation need to be
explained
Line 166 This in turn suggest; suggests and not suggest
The histological images are not of good quality; readers should be able to clearly
see the morphological details of the lymphoid infiltrate within the mucosa,
therefore higher magnification of HE and EBER is required.
