This is the submission form for our monthly Pathology case studies. Once the case becomes archived — when next month's case is revealed — we will post the correct answer under the Diagnosis heading.

Answers for each case should be submitted with a brief explanation of how you came to the conclusion of your diagnosis. You may also submit your own case study for possible future inclusion as the Case of the Month.

This question is for testing whether or not you are a human visitor and to prevent automated spam submissions.
