Andres Matoso, MD
Dr. Andrés Matoso, MD, is a Professor of Pathology, Urology, and Oncology at Johns Hopkins University School of Medicine and currently serves as Director of the Urologic Pathology Division and the Genitourinary Pathology Fellowship Program. He earned his medical degree from the University of Buenos Aires in 2002, followed by clinical training in urology at Hospital Militar Central in Buenos Aires. After moving to the United States, he completed a postdoctoral fellowship in cancer biology at Cornell University, where he investigated mechanisms of tumor biology and progression. Dr. Matoso subsequently pursued residency training in Anatomic and Clinical Pathology at Brown University, where he also completed a fellowship in gastrointestinal and liver pathology. He further specialized in urologic pathology through fellowship training at Johns Hopkins Hospital, before joining the Johns Hopkins faculty in 2017. Since then, he has become an integral leader of the Urologic Pathology Consult Service, which reviews more than 5,000 cases annually from national and international institutions, making it one of the largest such services in the world. In this role, he provides expert diagnostic consultation on highly complex and rare cases, and he is actively engaged in mentoring residents and fellows through advanced subspecialty training. Dr. Matoso’s research program focuses on the molecular and morphologic underpinnings of urologic malignancies, with particular emphasis on the genetic alterations associated with bladder cancer development and progression, refinements in prostate cancer grading, and the characterization of uncommon and diagnostically challenging urologic tumors. His translational research bridges molecular diagnostics and histopathology, contributing to improved classification, prognostication, and therapeutic stratification in genitourinary cancers. He has published extensively in the field, authoring more than 170 peer-reviewed scientific articles, seven book chapters—including authoritative contributions to the World Health Organization (WHO) classification of urologic and pediatric tumors—and a widely used textbook, Survival Guide to Prostate Pathology. His scholarly work has been recognized with several awards, including the prestigious Stowell-Orbison Award from the United States and Canadian Academy of Pathology. Beyond his research and clinical practice, Dr. Matoso is an internationally sought-after speaker and educator, lecturing widely at national and international scientific meetings, workshops, and academic institutions.
