NEW: User survey: (to help me learn how to make them better!)


NOTE: There is also now a convenient shorter URL:

Below are my notes for a range of conditions commonly encountered by surgical pathologists and cytopathologists.  I developed these as teaching aides for my resident didactic sessions and trainees at the University of California, Davis. 

My suggestions on wording for streamlined, user-friendly diagnostic report write ups can be found here
Flashcards based on these notes can be found here.

Disclaimer: These guides are produced by Kurt Schaberg primarily for studying purposes based on my reading. They represent a distillation and edited compilation of a broad range of resources created by other dedicated individuals, including edited text, criteria, hints, and figures from a variety of resources, including books (particularly the WHO Classification of Tumours series for tumors), scientific literature, websites, and social media. These are meant to be educational in a non-profit teaching lecture-like “fair use” context for the trainees at the University of California, Davis.  Some components may closely reflect a variety of source material to retain their educational essence. If you would like me to remove any material that you feel I have unfairly used or characterized, please let me know and I would be happy to work with you to remove it.  My goal is only to teach and share my joy of pathology and I make no money from this website (in fact, it costs me money ;-).

Although I try to keep them as accurate and up to date as possible, errors may exist. These should not be used for medical advice. As Dr. Bob Rouse (a mentor of mine while I trained at Stanford at the VA in Palo Alto, CA) would say: “Ein Buch ist ein Spiegel, aus dem kein Apostel herausgucken kann, wenn ein Affe hineinguckt.”
