Unusual and Challenging Cases in Genitourinary Pathology


This lecture will discuss uncommon variants of select genitourinary tumors of testis/paratesticular and renal/perirenal tissues with a focus on the differential diagnosis, key morphologic features, and when appropriate, ancillary testing.

Dr. Albertson is an associate professor of pathology at the University of Utah School of Medicine. He received his MD from the University of Nebraska and completed his residency in anatomic and clinical pathology at Creighton University, followed by a surgical pathology fellowship at the University of Utah. While at Creighton, Dr. Albertson served as the chief resident for two years and received the Hal Lankford Pathology Resident Award. He is a member of United States and Canadian Academy of Pathology and the College of American Pathologists. Dr. Albertson’s special research interest include oncologic genitourinary pathology.


After this presentation, participants will be able to:

  • Describe a differential diagnosis of epithelioid and gland/pseudogland forming tumors of the paratestis using gross, microscopic, and immunohistochemical testing
  • Identify key morphologic features and ancillary testing in the workup of paratesticular adipocytic tumors
  • Identify patterns of hereditary leiomyomatosis associated renal cell carcinoma/fumarate hydratase (FH) deficient renal cell carcinoma and the use of FH immunohistochemistry in the diagnostic workup of renal cell carcinoma
  • Describe a differential diagnosis of small round blue cell tumors of the kidney and understand key morphologic, immunohistochemical, and molecular (FISH) findings of primitive neuroectodermal tumor (PNET)
  • Identify unusual histologic variants of angiomyolipoma and immunohistochemical testing that may aid in the diagnosis
