Digital images were retrospectively reviewed by two uropathologists and compared with conventional haematoxylin and eosin\u2010stained FFPE sections. The primary endpoint was diagnostic concordance between FCM and histopathology in detecting invasive squamous cell carcinoma (SCC); secondary endpoints included sensitivity, specificity, and overall feasibility of image acquisition.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 29 FCM scans were obtained. Diagnostic image quality was achieved in 28\/29 scans (96.6%). FFPE analysis confirmed invasive SCC in eight patients, differentiated penile intraepithelial neoplasia in three, and an atypical squamous proliferative lesion (ASPL) in one. FCM correctly identified tumour category in 11\/12 patients, yielding an overall accuracy of 91.7% (95% confidence interval [CI] 61.5\u201399.8%). Sensitivity for invasive SCC detection was 87.5% (7\/8; 95% CI 47.3\u201399.7%), and specificity was 100% (4\/4; 95% CI 39.8\u2013100%). One SCC was misclassified as ASPL on FCM.
