Reviewer Comments:
In this manuscript, the authors reported on a rare case of cellular angiofibroma
(CA) arising in the retroperitoneal space. The location of the tumor and the fact
that it was discovered in a pregnant case were very rare and significant as a case
report. However, there were still some aspects of the paper that were not fully
described and discussed.
Specific critics are the following:
1) Tumor markers as a serological diagnosis are important in the differential
diagnosis of pelvic tumors. Tumor marker data should be clearly described in the
text.
2) If diffusion-weighted MRI results were available, they should be included in
the text.
3) What was the organ of origin of CA as a pelvic tumor? To which organ was
the stem of the tumor connected?
4) The timing of the tumor resection surgery was unclear. Was it before or after
the MRI taken 6 weeks after the miscarriage?
5) Were there any findings of compression of the urinary tract by the cellular
angiofibroma at the time of surgery? If so, a detailed description would be
appreciated.
