Since the seminal study of Hart and Helwig in 1975, there are few detailed pathological studies of lichen sclerosus (LS). The aims of this study were to provide a detailed histopathological description of penile LS, as well as to explore its relationship with penile intraepithelial neoplasia (PeIN) or invasive carcinoma. We evaluated 200 patients and designed a topographical approach for the histological evaluation focusing in alterations of the following anatomical layers: squamous epithelium, lamina propria, dartos, and corpus spongiosum. We documented the quantity and topographical location of stromal lymphocytes. The prevalent lesions found were epithelial hyperplasia, atrophy, PeIN, basal cell vacuolization, lamina propria sclerosis, and variable patterns of lymphocytic infiltration. Various unique patterns of stromal sclerosis were described: perivascular, globular, linear, and solid fibrosis/hyalinization; any of them were found to be diagnostic for LS. The variation in the topography and density of lymphocytes was determinant for the identification of LS morphological variants: lichenoid, band-like, lymphocytic depleted, and mixed. A major finding was the identification of the variant designated as lymphocytic depleted LS, which we considered as the morphological prototype of LS associated with penile neoplasia. The detailed description of this complex lesion presented in this study may help pathologists in practice to identify and better define LS. The identification of the special variants suggests a role of the stromal lymphocytes in the process of carcinogenesis. Confirmation of the observations with more studies is necessary to determine the significance of these findings.

Review
Lichen sclerosus (LS) is a severe, chronic, dermatosis characterised by inflammatory, sclerotic, pruritic lesions that causes significant morbidity in patients of all genders and ages. In boys, the lesions typically affect the foreskin and glans (termed balanitis xerotica obliterans (BXO)), leading to phimosis and potentially meatal stenosis. The incidence of the disease is not well reported but the average age of affected boys is 8 years (range 1-16). Diagnosis can often be made clinically, although histological study remains important to rule out important differential diagnoses. Complications include genital scarring, urinary and sexual dysfunction as well as the development of carcinomas in adult life. Circumcision has been regarded as definitive management of BXO in boys, but this may be supplemented with medical therapies such as topical steroids, immune modulators, intralesional triamcinolone and ozonated olive oil. Supportive measures including emollients, avoidance of irritants, surveillance of complications and recurrence as well as education and counselling remain important.Conclusion: BXO remains an important cause of phimosis in boys. The frequency of this condition appears unclear but seems likely to be less than 1% of males. Treatment generally involves circumcision, with some evidence that topical steroids or immunomodulators may decrease the incidence of recurrent meatal stenosis.What is Known:• Surgical circumcision is considered the definitive management of BXO• Many aspects of BXO are still in contention or require further study including the epidemiology and aetiology.What is New:• There is increasing awareness of non-surgical modalities that may be used in adjunct to surgery including topical corticosteroids, immune modulators, intralesional triamcinolone and ozonated olive oil• Awareness of meatal stenosis-related BXO has led to the development of surgical techniques such as preputioplasty as well as buccal mucosal inlay grafts.

Urology Jan 2020To elucidate current understanding on the pathophysiological mechanism of genital lichen sclerosus (LS), urologic manifestations, and treatment options.
OBJECTIVE
To elucidate current understanding on the pathophysiological mechanism of genital lichen sclerosus (LS), urologic manifestations, and treatment options.
MATERIALS AND METHODS
The Medline/PubMed and Embase databases were systematically reviewed for publications pertaining to LS. After applying inclusion and exclusion criteria, references were assessed for relevance to the pathophysiology, presentation, and treatment of LS by title and abstract review by 2 independent reviewers, yielding 186 articles for assessment.
RESULTS
The contemporary understanding of the epidemiology and histology of LS is reviewed herein. Additionally, we explore in detail the 3 hypotheses regarding the pathophysiological mechanism contributing to disease presentation: infectious etiology, primary immune dysregulation, and the isotraumatopic response. We summarize the available biological evidence supporting each hypothesis. This discussion provides context for understanding LS morbidity and may spur new avenues of research. For the clinician, we review the clinical presentation of disease, including the risk of progression to squamous cell carcinoma. The current medical and surgical treatment options are also detailed.
CONCLUSION
LS remains a potentially insidious disease which may lead to debilitating urinary and sexual dysfunction. Cross disciplinary research should aim for earlier detection, as well as more effective and durable treatment. The exact cause of LS remains unknown.

BACKGROUND
Symptomatic phimosis is a common childhood urology complaint. Circumcision was traditionally the treatment of choice, but its popularity in cases of non-scarred phimosis has been superseded by more conservative methods like preputioplasty. We sought to examine outcomes of preputioplasty for the treatment of non-scarred pathological phimosis in two UK paediatric surgery tertiary centres.
METHODS
Retrospective case series selecting cases performed in both departments over a 4 year period (January 2012-December 2015).
INCLUSION CRITERIA
non-scarred pathological phimosis treated with preputioplasty.
EXCLUSION CRITERIA
diffuse scarring of foreskin or presence of balanitis xerotica obliterans (BXO), preputioplasty performed as part of hypospadias repair. Outcome measure was treatment success as evidenced by fully retractile prepuce at follow up. Follow up occurred between 3 and 24 months.
RESULTS
We identified 126 patients, 6 were excluded due to the above criteria. Median age was 13.4 years (range 10 months-18 years). Median follow up was 13 months (range 3-24 months). 115 patients (96%) had successful treatment as evidenced by satisfactory post-operative cosmesis and complete resolution of phimosis at follow up. Recurrence of phimosis occurred in 5 patients (4%). Mean time of recurrence was 6 months, with a median age of recurrence of 15.3 years (range 10.7-16.7 years). All patients with recurrence were successfully treated with circumcision.
CONCLUSION
Foreskin conserving methods like preputioplasty are a valid option in the treatment of non-scarred pathological phimosis.

BACKGROUND
Lichen sclerosus (LS), (balanitis xerotica obliterans), causes pathological phimosis. Many boys present with obstructive symptoms, the cause is usually obvious on examination so ultrasound scans (USS) of the urinary tract are not routinely indicated. We review a series of abnormal USS in boys with LS.
METHODS
Retrospective note review for boys undergoing surgical treatment for LS between 2000 and 2017. Seventy-eight boys had a USS prior to surgery, those with abnormal USS form the study population. Boys with neuropathic bladder or congenital urinary tract abnormalities were excluded.
RESULTS
Nineteen of 78 boys (24%), mean age 9 years, were included. Seventeen had obstructive symptoms, 13 had culture proven UTIs, 12 had new onset incontinence. On USS 3 (17%) had acute retention, 8 (78%) had an isolated post-void residual volume (PVR) >10% of estimated bladder capacity (EBC); 3 had bladder wall thickening +/- PVR >10%, 5 had upper tract changes. Symptoms resolved with successful treatment of LS. Six boys had post treatment USS, abnormalities resolved in 5.
CONCLUSIONS
Clinicians should consider LS in boys presenting with UTIs, new onset incontinence and obstructive urinary tract symptoms. Routine USS are not indicated though should be considered in those with an atypical history or examination.
