Reviewer’s report
Title: 
Nodular malignant melanoma in vulvar skin without pigmentation: a case
report
Version:

Reviewer's report:
I appreciate the authors' efforts in revising the manuscript. I can understand that
amelanotic malignant melanoma may be rarely diagnosed in Asia, however,
there are several reports published worldwide. Hence, I still have concerns about
the interest of this case report to the readers worldwide. I also wonder how
"ultrasound B" can be used to detect the sentinel lymph node? Otherwise, the
authors have provided satisfactory response to my comments.
