Reviewer's report:
This is an interesting case report on Concurrent müllerianosis of the urinary bladder and the umbilicus
presenting with umbilical bleeding: a rare case report and review of the literature.
Abstract:
The authors should include the tribe.Eg Asian or European woman. What is the parity of the woman?
What is the import of this case report? Does the woman had cyclical umbilical menstruation? 
CASE PRESENTATION
The authors stated: 'These histological findings were consistent with endometrium 6 and endosalpinx,
and  a  diagnosis  of  müllerianosis  was  made'.  But  under  discussion  section,  the  authors  stated:
'Müllerianosis of the umbilicus in the present case appeared 3 irregular and firm. A histopathological
study revealed multiple foci of glands with variable size lined by tubal, endocervical, and 4 endometrial
epithelium situated in the lamina propria and muscularis propria'
The two statements appear incongruous. The authors should reconcile.
Conclusion:
I cannot see a conclusion in the case report.
The authors should include a conclusion statement in the manuscript
