Penile intraepithelial neoplasia (PeIN) and penile squamous cell carcinoma (PeSCC) are both thought to be associated with male genital lichen sclerosus and human papillomavirus (HPV) infection through dichotomous pathways: (i) undifferentiated PeIN and warty/basaloid PeSCC are thought to be HPV related, whereas (ii) differentiated PeIN and usual PeSCC are considered HPV independent. Tissue arrays were constructed from male genital lichen sclerosus, undifferentiated and differentiated PeIN, usual-type PeSCC, and unaffected tissues. Staining for p16 and for high-risk and low-risk HPV subtypes through RNAscope was performed.

Background: Male genital lichen sclerosus (MGLSc) is a chronic and acquired inflammatory dermatosis associated with substantial sexual dysfunction and urological morbidity and mortality. The age incidence of MGLSc is held to be biphasic, with a peak in infancy and another in adulthood. A recent review has implied two peaks in adulthood (making it triphasic overall); this triphasicity has been our emergent clinical impression from a voluminous practice.

Zoon balanitis (ZB) was originally described in the 1950s in patients with clinical features resembling erythroplasia of Queyrat, but with histology that demonstrated a plasma cell infiltrate without evidence of dysplasia. Subsequently, ZB has been extensively reported in the literature, reflecting widespread acknowledgement as an established distinct clinicopathological entity. However, its existence as such has been questioned and there have been suggestions in the literature that ZB represents either a non-specific irritant reaction pattern, or a part of the heterogenous clinicopathological complex of male genital lichen sclerosus (MGLSc).

Article Synopsis
  • Benign male genital pigmentation is often observed in men with male genital lichen sclerosus (MGLSc), but there is a lack of clear terminology and limited research on this topic.
  • The study examines 21 patients with MGLSc who have benign penile pigmentation, revealing that most patients reported pigmentation developing after their MGLSc symptoms, and the appearance of these pigmented areas remained stable over time.
  • The paper suggests that genital lentiginosis and melanosis may appear similar clinically, but there's a potential risk for penile melanoma in MGLSc patients; hence, it's crucial to approach pigmented lesions with a readiness for biopsy and follow-up.

Article Synopsis
  • - The study identifies the significant long-term psychological and quality-of-life impacts on adults diagnosed with Stevens Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN), beyond the well-documented physical effects.
  • - Through in-depth interviews with 18 adults, two main themes emerged: 'Psychosocial Impacts' and 'Chronicity of Sequelae', highlighting how SJS/TEN changes patients' views on life and affects their overall well-being.
  • - The research concludes that understanding the chronic nature of SJS/TEN is crucial for improving patient care and emphasizes the need for better psychological support and coordinated healthcare pathways after hospital discharge.

Background: Lichen sclerosus (LS) is a chronic, inflammatory skin disease with a predilection for the genitalia. Although, the association between squamous cell cancer and genital LS is well established, a link with genital melanoma has not been thoroughly explored. However, we have recently published a case series of penile melanoma where 9/11 (82%) of patients seen over a 10 year period with penile melanoma were retrospectively found to have histological and/or clinical evidence of genital LS on review.

We present a case of a 70-year-old gentleman who was referred to our tertiary 2-week-wait penile cancer clinic with a penile mass that was ulcerated, painful and discharging. This was suspicious for penile cancer and a radical circumcision was performed to remove the diseased foreskin en bloc with the lesion that was arising from the inner foreskin. Histopathology did not reveal cancer; however, we identified spirochaetes in keeping with syphilis.

Article Synopsis
  • The letter presents an interpretation of a published case report regarding a patient with chronic lichen sclerosus affecting the male genital area.
  • The authors emphasize that this condition is often undertreated, which can lead to serious complications.
  • If not properly managed, lichen sclerosus can lead to permanent tissue changes and increase the risk of secondary bacterial infections.

Human papillomavirus (HPV) is a common sexually transmitted infection with wide-ranging clinical manifestations. High-risk anogenital HPV genotypes have also been reported to cause extragenital disease. We describe the case of a 69-year-old male patient living with HIV who was diagnosed with HPV-16 associated Bowen's Disease (BD) of the right middle finger nailbed, despite good virologic control and immune reconstitution.

Background: There is a well-established association between squamous cell cancer and genital lichen sclerosus (GLSc). Although there have been several reported cases of vulval melanoma (MM) associated with LSc, particularly in the paediatric population, fewer cases of male genital (M) GLSc and penile (Pe)MM have been published.

Objectives: The aim of this study was to explore further the relationship between PeMM and MGLSc by reviewing all the cases managed by our multidisciplinary service over a finite period.

Fournier's gangrene is a rare, rapidly progressive, fulminant form of infective necrotising fasciitis of the genital, perianal and perineal regions. We present a case of Fournier's gangrene of the penis complicating acute genital ulceration and recurrent paraphimosis that was secondary to contemporaneous COVID-19 and Mpox infection in an otherwise healthy 41-year-old man. It is important for clinicians to be aware of Fournier's gangrene, as early detection remains the cornerstone of effective tissue and indeed life conserving management.

The epidemiology and potential pathogenic roles of human papillomavirus (HPV) and Merkel cell polyomavirus (MCV) in keratinocyte cancers (KCs) arising in people living with HIV (PLWH) compared with HIV-negative individuals are poorly understood. These issues were investigated by a case-control study in which the presence of MCV and HPV DNA was identified by polymerase chain reaction in microdissected formalin-fixed paraffin-embedded tissue from PLWH and HIV-negative individuals. The samples comprised 190 cutaneous and genital KCs/precancers (actinic keratoses, n = 43; cutaneous squamous cell carcinoma (cSCC) in situ, n = 24; basal cell carcinoma, n = 78; cSCC, n = 34; penile carcinoma in situ, n = 9; penile SCC, n = 2 from 104 individuals (PLWH, n = 51; HIV-negative, n = 53).

Social media were designed to connect people and support interpersonal relationships. However, whether social media use is linked to the connection between the self and others is unknown. The present research reviewed findings across psychology to address whether social media use is linked to defining and expressing the self as connected to others (i.

Background: Lichen sclerosus (LSc) is a chronic, inflammatory, destructive skin disease with a predilection for the genitalia (GLSc). An association with vulval (Vu) and penile (Pe) squamous carcinoma (SCC) is now well established but melanoma (MM) has only rarely been reported complicating GLSc.

Methods: We have performed a systematic literature review of GLSc in patients with genital melanoma (GMM).
