General Information

Continuing Medical Education The American Society of Dermatopathology is accredited by the Accreditation Council for Continuing Medical Education to provide continuing medical education for physicians. The American Society of Dermatopathology designates this live activity for a maximum of 35 AMA PRA Category 1 Credits™. Physicians should claim only the credit commensurate with the extent of their participation in the activity.

Continuing Medical Education Policy The American Society of Dermatopathology (ASDP) is accredited by the Ac- creditation Council for Continuing Medical Education (ACCME). As such, we are required to meet the ACCME’s expectations for our practice of continuing medical education.

It is the policy of the ASDP to ensure balance, independence, objectivity and scientific rigor in all of its educational activities. Faculty participating in and planning the Annual Meeting must comply with all procedures governing disclosure. The ASDP has implemented a process where everyone in a position to control the content of an educational activity will present evidence-based content, disclose all relevant financial relationships with any commercial interest and discussion of unlabeled/investigational uses of a commercial product. In addition, presentations must be free of commercial bias and any information regarding commercial products/services must be based on scientific methods generally accepted by the medical community. Conflicts were resolved prior to this educational activity. Faculty who refused to disclose relevant financial relationships and discussion of unlabeled/investigational uses of a commercial product would have been disqualified from participating in the planning and implementation of this CME activity.

Presenters who qualified for the implementation of this activity are required to disclose to the audience verbally and in writing, immediately prior to the scientific presentation, any of the relationships mentioned above. Faculty relationships are also disclosed in this program book.

CME Claims and Verification of Attendance Important! Attendees will be able to claim their CME credits online via the ASDP website after the meeting. You must submit your CME credit online in order to receive appropriate CME credit. The number of CME credit available for each course is indicated by the course title in this program and on the online CME submission site. A CME Tracker is included in this book on page 69. An official CME certificate will be available to print immediately after completing the online CME claim form and evaluation. Paper certificates will not be mailed.

Appropriate credit for attendance should be ascertained and reported by individual physicians to the particular state or medical society to which he/she belongs.

MelaPro Dx is a molecular profiling test used as an adjunct to histopathological examinations. It provides physicians with actionable intelligence when histopathology alone is insufficient for accurate diagnosis of melanocytic lesions.

This test will be broadly available to the dermatopathology community in late 2018. Please contact us to become an early adopter.

The first objective proteomic test to differentiate between malignant melanomas and benign nevi

The use of non-invasive imaging of skin lesions has the potential to change the practice of dermatopathology by shifting the types of biopsies performed and changing workflow, including ex vivo imaging of biopsies prior to routine histologic processing, and altering billing practices for dermatopathologists who participate in this cellular-level image interpretation. This course will explore basic principles, practice integration models and impact predictions, terminology, and en face imaging features of key inflammatory and tumoral lesions diagnosed by dermatopathologists, using RCM.

Topics discussed will include: ➜➜ Optimal terminology for reporting of margins – e.g., how do you handle the reporting of an infiltrative basal cell carcinoma that extends to within 0.2 mm of the examined inked margin? — (recommend re-excision, report distance to margin, etc.) ➜➜ Optimal terminology for histologically ambiguous lesions – e.g., what is your diagnosis for “SK versus condyloma” in the genital region? What additional factors do you take into consideration? ➜➜ Trigger points that prompt a diagnosis of squamous cell carcinoma rath- er than actinic keratosis, melanoma in situ vs. other types of melanocytic proliferation. ➜➜ When to request FISH and genomic studies in the setting of histologically ambiguous melanocytic neoplasia. ➜➜ How to best handle an inadequate specimen in a variety of situations. ➜➜ Explore optimal work up for lymphocytic infiltrates when lymphoproliferative disease is a consideration. ➜➜ And many other everyday situations.

.5 AMA PRA Category 1 CME CreditTM

Michael G. Hitchcock, MBChB, MBA President, American Society of Dermatopathology

From Rods and Cones to Diagnosis – What Could Possibly Go Wrogn? This year’s President’s Address will consider what is known about how our brains process visual inputs to formulate histologic diagnoses. Examples will illustrate how we un- consciously filter masses of inbound data, at times making shortcuts that bypass key diagnostic clues while philosophy fills the gaps in the science. The objective of the talk is to share knowledge about the instrument that we rely on most in our work, the gold standard of diagnostic equipment, the brain.

Upon completion of this lecture, participants should be able to: ➜➜ Recognize the limitations of what we know about how our brains formulate diagnoses and cognitive factors that may contribute to case misdiag- nosis. ➜➜ Improve diagnostic accuracy by identifying the strengths and circumvent- ing weaknesses of our cerebral diagnostic mechanisms.

Problematic Dermatopathology: What the Textbooks Don’t Teach

The challenges presented by dermatopathology are not Saturday, always in the realm of straightforward differential diag- November 10 nosis. Mixed-up specimens, misleading clinical information, deficiencies in specimens or the manner in which they are handled, and confounding historical and laboratory data occur all too frequently. This lecture will consider each of these and their significant impact on decision-making and patient care. Upon completion of this course, participants should be able to: ➜➜ Recognize and circumvent various factors that can complicate seemingly straightforward cases. ➜➜ Implement process improvements to address practice gaps, improving diagnostic accuracy and patient outcomes.

Short Course IV B-cell Lymphomas and Lymphoproliferative Disorders

Sunday, November 11 8:30 a.m. – Noon Grand Ballroom, 2nd Floor

Course Director: Melissa Pulitzer, MD Memorial Sloan Kettering Cancer Center

3.25 AMA PRA Category 1 CME CreditsTM

B-cell lymphoproliferative processes in the skin represent a diverse group of diseases, ranging from benign reactive infiltrates to high-grade malignancies. Although the features of B-cell malignancies can be diagnostic and straightforward, there are a number of potential pitfalls in the interpretation of B-cell infiltrates due to patient-related, disease-related and procedure-related factors. This course will address both clear-cut and difficult diagnostic entities. Specif- ically, well-characterized low-grade B-cell neoplasms, cutaneous involvement by extracutaneous or cutaneous B-cell lymphoma/leukemia and viral-related lymphoproliferative disease will be reviewed. Diagnostic foils in the evaluation of B-cell proliferations, including reactive or partially reactive processes and difficult immunophenotypic challenge will be discussed. Special attention will be given to immunophenotypic clues in teasing out complex proliferations. Sunday, November 11 Faculty and Course Outline
