Preanalytical processes in pediatric patients are generally manual and associated with a higher risk of error. The optimized delta check rules for detecting misidentified children samples are examined. Relative difference and absolute different delta check limits were applied on original and reshuffled (to simulate sample mislabeling/mix-up) paired...

To assess the clinicopathologic features of small renal masses (≤4 cm) associated with distant metastatic disease. We identified radical or partial nephrectomies with renal cell carcinomas (RCCs) measuring 4 cm or less in size (pT1a or pT3a) from 2005 to 2015. Clinicopathologic features were compiled. A total of 590 RCCs 4 cm or less were identifie...
