Case of the Month

Each Case of the Month is created for pathologists to share interesting cases, to collaborate on research and for educational purposes.

For each case of the month, you can submit your diagnosis. Feedback will be given the following month — once the case has moved to our archives.

If you would like to contribute a case to be featured here as a Case of the Month, please submit it.
