4:30pm-6:30pm UPDATE IN ADNEXAL NEOPLASMS Crystal I Ballroom

Course Directors: Doina Ivan and Luis Requena

Objectives: The diagnosis of cutaneous adnexal neoplasms is often challenging due to their complex

nomenclature and classification. The objective of this course is to introduce recently described entities in

adnexal proliferations, discuss a practical diagnostic approach of these tumors and expand the knowledge

in regard to their diagnosis. In addition, adnexal tumors may be associated with inherited syndromes and

visceral neoplasms. Early and correct recognition of these lesions is of upmost importance for patient’s

follow-up, prognosis and therapeutic options, especially since cutaneous lesions may be sometimes the

first manifestation of the disease.

Faculty:

Luis Requena: "Recently described entities in adnexal proliferations"

Doina Ivan: "Things are not always what they seem: how to avoid pitfalls in the diagnosis of

cutaneous adnexal tumors"

Omar Sangüeza: “Adnexal neoplasms associated to systemic diseases”

10:30am-12:00pm BEST IN The American Journal of Dermatopathology Crystal I BR Course Directors: Omar Sangüeza and Luis Requena

Objectives: Authors of articles with the highest total citation rate in The American Journal of

Dermatopathology (AJDP) (during 2010-2016) will present overviews of their papers. Emphasis will be

placed on how their goals and data affected the practice of dermatopathology and dermatology.

Effectively, this session will provide a broad update in the field of dermatopathology by covering a range

of disorders. Following this session, the attendee should be able to: 1. Critically examine key articles,

highly cited in the AJDP, which describe advances in dermatopathology. 2. Recognize and apply new

dermatopathologic approaches to the diagnosis of skin disease. 3. Appreciate the importance of clinical-

pathologic correlation for the diagnosis of skin disease.

Division of Pathology/Lab Medicine

Anderson Clinical Faculty Chair for Cancer Treatment and Research

The University of Texas - MD Anderson Cancer Center, Houston, TX

“Application of Liquid Biopsies to Pathology Diagnosis: No Longer a Future Possibility”

2:30pm-4:30pm SYSTEMIC DISEASES UNDER THE MICROSCOPE Crystal I Ballroom

Course Directors: Dieter Metze and Anjela Galan

Objectives: During this session, the attendees will advance their knowledge of systemic cutaneous

diseases, including lupus erythematosus, panniculitis, endocrine and metabolic disorders, critically ill

patients, as well as alerting inflammatory patterns, and a comprehensive review of pruritus.

Faculty:

Anjela Galan: Lupus Erythematosus: What Lies Beneath

This lecture will focus on updates in pathogeneses of lupus erythematosus, helpful microscopic features,

and unusual presentations that can lead to diagnostic pitfalls.

Margot Peters: Panniculitis: Systemic or Localized (Sub)Cutaneous Disease?

Case-based approach to subcutaneous pathology to better understand when panniculitis is a manifestation

of systemic as compared with localized disease.

Franco Rongioletti: Skin Signs of Endocrine and Metabolic Disorders Under the Microscope

Although endocrine and metabolic diseases are regularly included in general textbooks of dermatology,

one gains the general impression that these topics receive little emphasis from a dermatopathological

point of view. In this setting, clinico-pathological correlation is essential.

Almut Böer-Auer: "Warning light: Patterns and Clues that put on the Alert"

Based on selected cases, this lecture intends to highlight patterns that should always prompt clinical

correlation and examination for associated systemic diseases. The patterns include neutrophil-rich

infiltrates (e.g., neutrophilic urticarial dermatosis, Sweet-like infiltrates), histiocyte-rich infiltrates (e.g.,

sarcoidal granulomatous, xanthogranulomatous, Langerhans-cell-rich), and some quite subtle, easily

overlooked surprises!

Jeffrey North: Inpatient Dermatopathology: Instructive Cases from the Hospital Ward

This lecture will focus on histopathology of critically ill patients and how to work through differential

diagnoses of various blistering and inflammatory dermatoses.

Dieter Metze: Pruritus Under the Microscope

Pruritus is one of the most distressing symptoms of internal, neurological, systemic and dermatologic

diseases. The lecture focuses on major progress in neurophysiology, understanding of the clinical aspects,

pathologic features, classification of pruritus, and novel diagnostic tools (bioptic evaluation of

intraepidermal nerve density).

5:00pm-6:30pm "IN THIS RING, WOMEN WARRIORS' MATCH" Crystal I Ballroom

Referee: Omar Sangüeza

Four teams of three each, drawn at random from the "contenders" below,

will face off in this Match! Good luck teams!

Objectives: At the conclusion of the "Match", the participants should be able to:

1) Envision the clinical appearance of lesions based on the history and descriptive narratives provided

with each specimen. 2) Formulate a differential diagnosis, using the history and clinical description prior

to reviewing the histology. 3) Understand the basic concepts, including background, clinical and

histological features and treatment, pertaining to each case. 4) Comprehend the importance and necessity

of clinical correlation in relation to microscopic findings to provide a correct diagnosis. 5) Expand

knowledge of a wide variety of cutaneous disease processes, including neoplasms, inflammatory,

infectious, and autoimmune diseases.
