Course Description
The Arthur Purdy Stout Society of Surgical Pathologists and USCAP continue their collaborative commitment to providing superb education for practicing pathologists. The Sixth Edition of Modern Surgical Pathology Through the Expert Eyes of APSS-USCAP is designed to eliminate a variety of practice gaps in diagnostic surgical pathology. The faculty’s review of the literature and collective clinical experience as consultant surgical pathologists have revealed areas that remain problematic for pathologists. Examples include the evaluation of invasion in biopsies of the genitourinary tract and cervix, the classification of inflammatory conditions of the skin, the distinction between neuroendocrine tumors of the GI tract, the differentiation between reactive and neoplastic changes in the female genital tract, and the differential diagnoses of problematic breast tumors.

This course attempts to help pathologists eliminate diagnostic errors by highlighting pitfalls and providing approaches to resolve them using routine microscopic examination and immunohistochemistry. The roles of adjunctive molecular tests will be discussed as appropriate. Thus, this course will address both medical knowledge and competence with the goal of improving clinical practice.

This course is a collaboration between the Arthur Purdy Stout Society of Surgical Pathologists (APSS) and USCAP.

This course offers digital slides for each case presented. You can view the case history and whole slide image (WSI) as unknowns by selecting Pre-session Slide Preview, or you can refer to the slides as you watch each video.
Target Audience

Practicing academic and community pathologists, and pathologists-in-training

Learning Objectives

Upon completion of this educational activity, learners will be able to:

  • Eliminate diagnostic errors by recognizing typical pitfalls and utilizing provided approaches to resolving these pitfalls in surgical pathology using both routine microscopic examination of H&E-stained sections and immunohistochemical stains.
  • Discuss the uses and limitations of immunohistochemistry in diagnostic surgical pathology.
  • Discuss the role of newer adjunctive molecular tests where appropriate.
  • Address both medical knowledge and competence with the goal of improving clinical practice.
