Primary squamous cell carcinoma of the scrotum: Outcomes from a specialist center.

BACKGROUND: Squamous cell carcinoma (SCC) of the scrotum is a rare and aggressive cancer. There are no established guidelines on the management of scrotal SCC. OBJECTIVE: To analyze the clinical management and outcomes of scrotal SCC. PATIENTS AND METHODS: A retrospective analysis of patients diagnosed with primary scrotal SCC over a 10-year period was performed. The type of surgery, tumor stage and histological subtypes, recurrence rate and metastases, cancer-specific mortality (CSM), and other-cause mortality (OCM) were analyzed. RESULTS: Between 2012 and 2022, a total of 10 men were identified with primary scrotal SCC. The median (interquartile, IQR) age was 65.5 (55-77) years. Wide local excision was performed in 9 patients and 1 patient underwent a total scrotectomy. The pathological T-stage was: pT1, n = 3; pT2, n = 1; pT3, n = 5 (50%); pT4, n = 1. Four patients had pathologically positive inguinal lymph nodes and 2 had distant metastatic disease at presentation. At a median (IQR) follow-up of 10.5 (4-31) months 5 patients died, of which 3 died from scrotal SCC. CONCLUSION: Scrotal SCC is extremely rare in the UK with only 10 primary cases identified in our center over the past 10 years. Surgical resection of the tumor and appropriate inguinal node staging are required due to a high proportion of cases which metastasize to the inguinal lymph nodes. PATIENT SUMMARY: Scrotal cancer is rare. 10 cases were diagnosed over 10 years at a single center. Around half had disease spread to the groin nodes or distant organs at presentation. Surgical resection was required in all patients. At the time of analysis, half of the patients are alive. Due to the rarity and aggressiveness of the cancer, management should be carried out within a specialist center.

Impact of COVID-19 pandemic on acute dermatology referrals in a secondary and tertiary care Central London hospital. A retrospective comparison review of pre-COVID-19 era and COVID-19 pandemic.

BACKGROUND: Although Dermatology is largely considered an outpatient specialty, there is an increasing need for Dermatology input in the acute and inpatient setting. During the COVID-19 pandemic, Dermatology services had to be reorganized to facilitate staff redeployment and minimize the risk of exposure to COVID-19 for patients and staff. This led to an unprecedented increase in teleconsultations aided by clinical images. OBJECTIVES: The main aim of our retrospective study was to analyse the acute Dermatology referrals received in the pre-COVID-19 era and during COVID-19 pandemic. METHODS: We retrospectively analysed acute Dermatology referrals using the acute referral log. RESULTS: We retrospectively analysed 500 and 110 acute Dermatology referrals received in the pre-COVID-19 period and during COVID-19 pandemic, respectively. In the pre-COVID-19 era, consultations were most commonly requested by Oncology/Haemato-Oncology, Emergency Departments and General Practice, while during the COVID-19 pandemic General Practice was the most common source of referrals. A wide variety of dermatological conditions were encountered with the most common been eczematous dermatoses. CONCLUSIONS: Although Dermatology is largely an outpatient-based specialty, this study shows the demand for urgent Dermatology input the care of sick patients with severe skin diseases and in the management of skin problems in patients admitted or receiving treatment for other diseases. Re-organization of Dermatology services during the COVID-19 pandemic resulted in a marked increase in teleconsultations (28% versus 84.5%) and highlighted the importance of complete skin-directed physical examination by the referring clinician as well as procurement of good quality clinical images.

Gene expression profiling in male genital lichen sclerosus.

Male genital lichen sclerosus (MGLSc) has a bimodal distribution in boys and men. It is associated with squamous cell carcinoma (SCC). The pathogenesis of MGLSc is unknown. HPV and autoimmune mechanisms have been mooted. Anti extracellular matrix protein (ECM)1 antibodies have been identified in women with GLSc. The gene expression pattern of LSc is unknown. Using DNA microarrays we studied differences in gene expression in healthy and diseased prepuces obtained at circumcision in adult males with MGLSc (n = 4), paediatric LSc (n = 2) and normal healthy paediatric foreskin (n = 4). In adult samples 51 genes with significantly increased expression and 87 genes with significantly reduced expression were identified; paediatric samples revealed 190 genes with significantly increased expression and 148 genes with significantly reduced expression. Concordance of expression profiles between adult and paediatric samples indicates the same disease process. Functional analysis revealed increased expression in the adult and child MGSLc samples in the immune response/cellular defence gene ontology (GO) category and reduced expression in other categories including genes related to squamous cancer. No specific HPV, autoimmune or squamous carcinogenesis-associated gene expression patterns were found. ECM1 and CABLES1 expression were significantly reduced in paediatric and adult samples respectively.
