Description: Twenty-five genitourinary or dermatology cases (representing 31 individual parts) were selected randomly by the LIS. Cases 32, 34 and 41 were vasectomy specimens that were removed before the study began and replaced by more challenging cases (chosen at random). The 142 slides represented those originally cut on the case and did not include recuts and special stains ordered by the original sign-out pathologist. As part of their workup, the study pathologists ordered 68 recuts and special stains, making the total number of slides imaged in the study 210. "High Level Diagnosis" is the summary/abstraction from the first line from the original, sign–out diagnosis and can be used to judge the nature of the cases studied.
TURP = Transurethral resection of prostate
TURB = Transurethral resection of bladder tumor
