BackgroundLichen sclerosus (LS) in men commonly involves the external genitalia, with up to 20% of these patients developing urethral stricture disease, and a small group developing malignant transformation to penile squamous cell carcinoma (SCC). The objective of this study was to determine the prevalence of LS and its sequelae in males presenting for circumcision. MethodsA multicentre retrospective cohort study was conducted at 8 hospitals within 3 Australian regional centres. We identified males who underwent circumcision between January 2004 and November 2018 and obtained histological and clinical data. Histopathological confirmation of LS was the primary outcome. Development of urethral stricture disease and penile cancer were secondary outcomes. ResultsSix hundred and eleven patients underwent circumcision, of which 313 (51.2%) had a specimen sent for histology. Of these, 199 (63.6%) had confirmed LS where the median age at diagnosis was 65 years [interquartile range (IQR), 40-77]. Even if the remainder of unsent specimens were free of LS, the prevalence would still be 32.6%. Amongst the patients with LS, 44 (22.1%) developed urethral strictures, 1 penile SCC (0.5%), and 1 penile intraepithelial neoplasia (0.5%). ConclusionsThe prevalence of LS in patients undergoing circumcision where the foreskin was sent for histopathological review was 63.6%. In those with LS, the prevalence of urethral stricture disease was 22.1%.
