Challenging pathology cases,before you see the answer.
Verified pathologists publish their most challenging cases with clinical history, full-magnification microscopy and immunohistochemistry. You commit to a diagnosis first, then see the final answer, the differential diagnoses and your colleagues' comments.
Three steps to a sharper diagnosis
Study the case
Review the clinical history, gross findings and images at full magnification, just as you would at the microscope.
Submit diagnosis
The final answer stays hidden until you submit your diagnosis — even from the page source. Then see how colleagues answered.
Scientific discussion
Read the differential diagnoses, teaching points and the contributor's notes, and share your questions or experience.
Images and whole-slide scans you can zoom down to cellular detail.
The diagnosis is not sent to your browser until you answer.
Every case is reviewed by the scientific editor before publication.
Metadata and identifying information are removed at every upload step.
