Check the current list of cases to ensure your case is not a duplicate. If we use the case, we will list you as the contributor and send you $50 (US dollars) by check or PayPal for your assistance. Note: the US government requires us to send it 30% of all payments sent to non-US residents, so we will send only $35 to non-US contributors.

When we receive your case and images, we will add them to a queue of pending cases and send you an email notification 1-2 weeks before your case will be posted on the website. Please do not contribute more than 3 cases per year.

To maintain quality control, we ask all contributors to get a second pathologist to confirm the diagnosis. Please provide confirmation of this upon submission of your case to PathologyOutlines.com.
