The inclusion of material on this site constitutes recommendations of material that may be beneficial to the trainees and practitioners in various subspecialties in Pathology and Laboratory Medicine. Inclusion does not represent an endorsement by the American Board of Pathology and exclusion should not be viewed as disapproval. It is simply not possible to include all relevant material. Textbooks are purposefully not included, with a few exceptions (e.g., WHO documents)."
