Course Description

Dermatopathology is a relatively specialized area of pathology requiring additional training; however, skin specimens are commonly encountered in the general surgical pathology practice, frequently constituting a large proportion of the total number of biopsies signed by general surgical pathologists. Accurate diagnosis of these cases entails knowledge of the vast array of potential diagnoses as well as competence in recognizing the histologic clues, which are often subtle, and in integrating the clinical findings. For the practicing pathologist lacking subspecialized training in dermatopathology, diagnosing these specimens may present a daunting task, especially for the less common diseases. In addition, in our age of precision medicine, the information one needs to include in the pathology report often involves ancillary molecular testing. Molecular discoveries with applications in diagnosis, prognosis and management are reported regularly within the literature, and yet, the typical practicing pathologist cannot easily distill this information to that which will meaningfully aid in diagnosis and/ or impact patient care. To this end, the aim of this course is to present the audience with relatively common dermatopathologic lesions and a focus on those entities that create challenges in diagnosis and / or have significant clinical implications. The course will provide a practical approach to common issues encountered in dermatopathology. The audience will be presented with the salient features of each entity, a choice of relevant ancillary tests and tips to avoid misdiagnosis. The course is intended for general surgical pathologists, junior dermatopathologists and pathology residents and fellows.

Course Co-Director

Dr. Andea is a Professor of Pathology and Dermatology and Director of the Dermatopathology Fellowship at the University of Michigan in Ann Arbor, MI. Dr. Andea's areas of expertise are Dermatopathology and Molecular Pathology. Dr. Andea received his M.D. from “Victor Babes” University of Medicine, Timisoara, Romania and completed an Anatomic and Clinical Pathology Residency at Wayne State University in Detroit, Michigan. This was followed by fellowships in Dermatopathology at Medical University of South Carolina, Charleston, SC and Oncologic Pathology and Molecular Pathology at Memorial Sloan-Kettering Cancer Center, New York, NY. After completing his training, Dr. Andea joined the faculty of the Department of Pathology at the University of Alabama at Birmingham (UAB) where he served as Director of the Dermatopathology Fellowship program, Medical Director of the In-situ Hybridization Laboratory and as Dermatopathology Section Head. In 2009 he received the “Leonard H. Robinson” Award for Excellence in Resident Education in Anatomic Pathology. At UAB Dr. Andea developed a research interest in the molecular biology of melanocytic neoplasms and precision molecular diagnostic tests for histologically ambiguous melanocytic tumors. While at UAB, Dr. Andea earned a Master of Business Administration degree from UAB School of Business.

At the University of Michigan, Dr. Andea has established and is leading the Molecular Dermatopathology Research Laboratory which functions as a dermatopathology core facility for skin cancer research and the Dermatopathology Molecular Diagnostics Laboratory providing clinical testing for melanocytic tumors. Dr. Andea has a particular interest in developing and improving ancillary molecular tests to help classify and predict prognosis in histologically ambiguous melanocytic tumors.

Course Co-Director

Dr. Prieto is a tenured Professor of Pathology and Dermatology at the University of Texas MD Anderson Cancer Center (MDACC), in Houston, TX. He received his M.D. and Ph.D. (Cellular Biology) degrees from the University of Alicante and University of Barcelona, respectively, both in Spain. After coming to the United States, he completed a residency in Pathology and a fellowship in Dermatopathology at Cornell University in NY City under Dr. Scott McNutt and a fellowship in Oncologic Pathology (Surgical Pathology) at Memorial Sloan Kettering Cancer Center under Dr. Juan Rosai. He then joined Duke University, Durham, NC as an assistant professor. After 3 years, in 1999, he became the section chief of Dermatopathology at MDACC, where he remained until 2016. He became the chair of the Department of Pathology in 2015.

Dr. Prieto’s interests are primarily in melanocytic and other neoplastic diseases in the skin, particularly in the use of immunohistochemistry for the diagnosis and prognostic evaluation of such diseases.

Dr. Prieto has been strongly committed to academic medicine and is or has been either editor or member of several of Pathology and Dermatopathology scientific journals. He has also participated in the administrative work of the ASDP society in both the Executive Committee and the Peer-Review and Mentorship Awards Committees. He is the Secretary-Treasurer of the International Society of Dermatopathology. He is currently the co-director of the Long Course of the USCAP Annual Meeting.
