Reviewer's report:
This manuscript titled "Epidermoid cyst in intrapancreatic accessory spleen in
the pancreas head: A case report." is an interesting report, and this case is very
rale and worth being reported. However, this paper would be better if the authors
revise this paper according to my suggestions. My suggestions are described
below:
1) This case is rare, and any imaging findings of this patient are important.
Therefore, if possible, the images of abdominal ultrasonography and endoscopic
ultrasonography should be presented as the Figure.
2) As the authors commented, most of the ectopic spleen is located around the
spleen, such as the splenic hilum, greater omentum, and pancreatic tail. Why was
the ectopic spleen located in the pancreatic head in this case? It may be due to
trauma, or false fusion of the splenic bud during embryonic phase. The authors
should discuss about it.
3) In page 6, line 17 to 22, the authors described about EUS-FNA and distal
pancreatectomy. But these are not discussed well. Especially, EUS and EUS-
FNA is important for correct diagnosis of ECIPAS, so the author should discuss
about it in more detail.
