Reviewer's report:
This is an interesting case report of eosinophilic peritonitis that could be related
to colon cancer. It is a well-documented paper even though the authors failed to
provide with a thorough assessment of eosinophil counts per high-power field
(HPF).
As mentioned in the manuscript, HPF means high-power field of the microscope.
However, the author should write out the specific magnification (x400? or
x600?) and the model number of microscope. Because different microscopes
have its own field area, which will affect the number of eosinophil counts. As the
author comes from Japan, I guess they use Olympus microscope. For example,
the microscopic area of Olympus BX53 microscope (26.5 field) is 0.345mm² per
HPF (x400), but the microscopic area of Olympus BX51 microscope (22 field) is
only 0.237mm² per HPF (x400).
PS: English language, grammar, and syntax needs quite extensive review,
particularly, in the case presentation and discussion.
