Cytologic and Small Biopsy Diagnosis of Kidney Tumors

 

This is a case-based presentation focusing on diagnosis of common kidney tumors using cytology and small biopsy specimens. Before reviewing individual cases, common indications for kidney biopsy, accuracy of diagnosis, and adequacy including rapid on-site-evaluation (ROSE) will be briefly discussed. Additionally, cytology of normal renal elements is included, as there can be significant cytomorphologic overlap with certain neoplastic lesions.

Originally presented on February 7, 2023, in Park City, Utah.

Objectives

After this presentation, participants will be able to:

  • Identify the most common indications for kidney fine needle aspiration (FNA)/core needle biopsy (CNB)
