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.
