Urologic Pathology: A Potpourri of Challenging Cases


Through a case-based approach, the goal of this presentation is to consider a series of entities from most major urologic organs. These particular cases have been selected either because they may cause particular diagnostic challenges, or because they may have specific clinical or genetic implications. The aim is to present an approach to these cases, including the morphologic findings (which in several of the cases are quite distinctive), together with immunophenotypic findings, and any relevant molecular or genetic findings.

Dr. Marc Barry is a medical director of anatomic pathology at ARUP Laboratories and an associate professor at the University of Utah School of Medicine. He received his medical degree from University College Dublin before completing an anatomic pathology residency at the Brigham and Women’s Hospital. Following his residency, Dr. Barry completed a post-doctoral research fellowship at the Massachusetts Institute of Technology. He then continued on to finish both a medical renal pathology fellowship and a urologic pathology fellowship at Brigham and Women’s Hospital. Dr. Barry is board certified in anatomic pathology and is affiliated with several professional organizations, including the United States and Canadian Academy of Pathology, the American Society for Clinical Pathology, and the College of American Pathologists. He is also the recipient of multiple awards, including the Registrar’s Prize for Research from the Royal Academy of Medicine in Ireland, the Research Scholarship Award from the College of American Pathology Foundation, and for Excellence in Urologic Resident Education from the University of New Mexico. Dr. Barry’s research interests include clinicopathologic questions in medical renal and urologic pathology as well as epidemiologic and translation aspects of urologic neoplasia.


After this presentation, participants will be able to:

  • By initial morphologic assessment, formulate a reasonable differential diagnosis for these challenging cases
  • Describe the role of particular ancillary studies in sharpening or resolving the differential diagnoses, including appropriate panels of immunohistochemical stains, cytogenetic, or molecular studies
  • Discuss the clinical relevance of the diagnoses, in terms of therapeutic implications, and in several of the cases, the specific possible genetic/syndromic implications for the patient
