Reviewer’s report
Title: 
Synchronous “skip” facial metastases from colorectal adenocarcinoma. A
case report and review of literature
Version: 
0 
Date:

Reviewer's report:
The authors showed the facial metastases from colorectal adenocarcinoma.
To accept this case as a rare case, I think that it is necessary to perform PET
evaluation.
In addition, the diagnosis of pathology was signet ring cell carcinoma which
tends to be malignant prognosis. And LN metastasis was observed, so I think it is
not rare to observe skin metastasis.
