Penile squamous cell carcinoma (pSCC) is a rare malignancy with a slowly increasing incidence and variable prognosis. Regional lymph node involvement signifies poor prognosis but represents a late sign, and more prognostic markers for effective patient risk stratification are urgently needed. In this retrospective study, 152 tumour samples with formalin-fixed, paraffin-embedded tissue were analysed for traditional pathological variables, tumour budding, p53, p16, and mismatch repair proteins (MMR) immunohistochemistry. The density of tumour lymphocytic infiltrate was also determined, using subjective evaluation by two pathologists (brisk/non-brisk/absent) and also using the immunoscore method, which categorised the cohort into five immunoscore groups according to the number of CD3+ and CD8+ T-cells in both the tumour centre and tumour invasion front. Only one case (0.6%) was MMR-deficient. Tumour budding count ≥5 tumour buds/20× power field and non-brisk/absent lymphocytic infiltrate were significant negative predictors of both the overall survival (OS) and cancer-specific survival (CSS), whereas a low immunoscore was a significant marker of shorter OS but not CSS. Advanced pT stage (3+4) was a significant marker of shorter CSS but not OS. In the multivariate analysis, high-grade budding was a significant parameter if adjusted for the patient's age and associated variables, except for the pN stage. The lymphocytic infiltrate retained its prognostic significance if adjusted for age and associated variables. The negative prognostic significance of the previously described parameters (lymphatic, venous, and perineural invasion, regional lymph node metastasis, and p53 mutated profile) were confirmed in our study. Grade, histological subtype, and HPV status (as determined by p16 immunohistochemistry) showed, surprisingly, little or no prognostic significance.

Review
The classification of the epithelial tumors of the male and female urethra includes benign and malignant neoplasms. Primary urethral carcinomas and adenocarcinomas of the accessory glands are the most relevant tumors, both from the morphologic and clinical point of view. An accurate diagnosis, grading and staging are essential for determining adequate treatment strategies and outcome. Information on anatomy and histology of the urethra is of fundamental importance in understanding the morphology of the tumors, including the clinical importance of their location and origin.

BACKGROUND
Carcinoma penis is a rare neoplasm, and the literature is scarce on long-term survival and its predictors. The aim of the study was to determine the clinical profile and management patterns, identify predictors of survival, and the impact of education and rural/urban dwelling on survival.
METHODS
Patients with a histological diagnosis of carcinoma penis from January 2015 to December 2019 were included in the study. Demographics, clinical profile, education status, primary residence address, and outcomes were obtained from the case records. Distance from the treatment centre was obtained from the postal code. The primary objectives were to assess relapse-free survival (RFS) and overall survival (OS). The secondary objectives were to identify the predictors of RFS and OS and to determine the clinical profile and treatment patterns in patients with carcinoma penis in India. Time-to-event was calculated by Kaplan-Meir analysis and survival was compared by the log-rank test. Univariate and multivariable Cox regression analyses were used to find independent predictors of relapse and mortality. Logistic regression analyses to examine the associations of rural residence, education status, and distance from the treatment centre with the relapse adjusting for measured confounding variables.
RESULTS
Case records of 102 patients treated during the above period were retrieved. The median age was 55.5 (interquartile range [IQR] 42-65 years). Ulcero-proliferative growth (65%), pain (57%), and dysuria (36%) were the most common presenting features. Clinical examination or imaging revealed inguinal lymphadenopathy in 70.6% of patients, however, only 42% of these lesions were pathologically involved. A total of 58.8% of patients were from rural areas, 46.9% had no formal education, and 50.9% had a primary residence ≥100 km from the hospital. Patients with lower education and rural households had higher TNM stages and nodal involvement. Median RFS and OS were 57.6 months (15.8 months to not reached) and 83.9 months (32.5 months to not reached), respectively. On univariate analysis tumor stage, involvement of lymph nodes, T stage, performance status, and albumin was predictive for relapse and survival. However, on multivariate analysis, the stage remained the only predictor of RFS and nodal involvement, and metastatic disease was a predictor of OS. Education status, rural habitation, and distance from the treatment centre were not predictors for relapse or survival.
CONCLUSIONS
Patients with carcinoma have locally advanced disease at presentation. Rural dwellings and lower education were associated with the advanced stage but did not have a significant bearing on the survival outcomes. The stage at diagnosis and nodal involvement is the most important predictor of RFS and OS.

Although uncommon, penile carcinoma can be a debilitating disease with various causes, and cancer is a significant contributor to morbidity and mortality in individuals infected with HIV. Verrucous carcinoma, a subtype of epidermoid carcinoma, is typically slow-growing and has a low propensity to metastasize. We present a case study of a 55-year-old HIV-positive patient with a massive squamous cell carcinoma of the penis that had been developing for over two years. To treat the condition, the patient underwent a total penectomy, perineal urethrostomy, and bilateral inguinal lymphadenectomy.

BACKGROUND
Human papillomavirus (HPV) infection, a common sexually transmitted disease, is associated with cancers of the cervix, vulva, vagina, penis, anus, and head and neck. Oropharyngeal squamous cell carcinoma (OPSCC; throat cancer) is a type of cancer involving the head and neck area that is rapidly increasing across the globe. There are higher rates of OPSCC among Indigenous populations relative to non-Indigenous Australian populations, although the HPV-attributable fraction remains unknown. For the first time at a global level, we plan to extend an Indigenous Australian adult cohort to monitor, screen, and ultimately prevent HPV-associated OPSCC and to undertake extensive cost-effectiveness modelling around HPV vaccination.
OBJECTIVE
This study aims to (1) extend follow-up to a minimum of 7 years post recruitment to describe the prevalence, incidence, clearance, and persistence of oral HPV infection; and (2) conduct clinical examinations of the head and neck, oral cavity, and oropharynx and collect saliva samples for early-stage OPSCC testing.
METHODS
We will continue to implement a longitudinal design for the next study phase, where we will ascertain the prevalence, incidence, clearance, and persistence of oral HPV infection at 48, 60, and 72 months; undertake clinical examinations/saliva assessments to detect early-stage OPSCC; and refer for treatment. The primary outcome measures are changes in oral HPV infection status, biomarker measures of early HPV-related cancer, and clinical evidence of early-stage OPSCC.
RESULTS
Participant 48-month follow-up will commence in January 2023. The first results are expected to be submitted for publication 1 year after 48-month follow-up begins.
CONCLUSIONS
Our findings have potential to change the way in which OPSCC among Australian Indigenous adults is managed, with desired impacts including cost-savings on expensive cancer treatments; improved nutritional, social, and emotional outcomes; and improved quality of life for both Indigenous adults and the Indigenous community more broadly. Continuing a large, representative Indigenous adult cohort to track oral HPV infection and monitor early OPSCC is essential to yield critical information to include in the management armamentarium of health and well-being recommendations for Australia's First Nations.

Bowenoid papulosis is a cutaneous disease that is part of the spectrum of genital in situ carcinomas, caused primarily by infection with oncogenic strains of the HPV virus. The potential to transform into squamous cell carcinoma requires the diagnosis and treatment of the lesions. We present the case of a 34-year-old non-smoker without medical history who presented to our clinic for the appearance of multiple, asymptomatic, well-defined, flat, pigmented violaceous papules at the root of the penis in evolution for a year. Reflectance confocal microscopy (RCM) suggested the diagnosis of bowenoid papulosis, which was confirmed by histopathological examination. The treatment with Imiquimod 5% (3 times/week) and Isoprinosine (4 g/day) was initiated, followed by monitoring of the lesions by repeated RCM examination. The evolution of the patient at 6 weeks of therapy was favourable, with clinical remission of lesions and improvement in RCM aspects of the evaluated skin. In conclusion, RCM represents a useful noninvasive examination method that allows not only the diagnosis but also the follow-up of the treatment response in order to decide the appropriate length of therapy.

INTRODUCTION
Data shows that bladder cancer (BC) takes the seventh place as the most commonly diagnosed when it comes to the male population. Whereas when both genders considered, it moves down the tenth place. Although 75% of patients with BC present with the disease confined to the mucosa or submucosa, rarely secondary metastasis to the penis occurs.
CASE PRESENTATION
A 73-year-old male was referred for gross hematuria in May 2018. A cystoscopy was performed detecting a bladder tumor. The resection of the tumor revealed an invasive high-grade (HG) papillary transitional carcinoma of the bladder with nest variants and lamina propria invasion. The histological examination of the second-look resection disclosed the same tumor characteristics. The patient was scheduled for bacillus Calmette-Guérin (BCG) instillations. Meanwhile, he was diagnosed and treated for a primitive lung acinar adenocarcinoma. Seven months after the first diagnosis, the patient progressed to cT4 at the level of the bladder. He underwent four cycles of Methotrexate, Vinblastine, Doxorubicin (Adriamycin) and Cisplatin (MVAC) chemotherapy followed by a cystoprostatectomy. The histological result was fibrosis and ypT0pN0 classification. Due to pain and solid mass in the penis, a total penectomy was performed and the histological result showed a transitional carcinoma suggesting a metastasis of the urothelial carcinoma of the bladder. Three months following the penectomy, a positron emission tomography∕computed tomography (PET∕CT) scan results showed multiple metastases and positive lymph nodes. Hence, Pembrolizumab treatment was started, providing very good clinical and radiological evolution. At the time of publishing, the patient is alive, and the radiological exams show stability of the disease.
CONCLUSIONS
The detailed descriptions of all histological variants of carcinoma of the bladder in the specimen has great importance and significant impact on the management of the disease.

Ossifying fibromyxoid tumors (OFMTs) are rare mesenchymal neoplasms which typically present in the superficial subcutaneous tissues and have not been reported to arise in visceral organs. We now report 4 molecularly confirmed cases of OFMT involving the genitourinary tract. All patients were males, ranging in age from 20 to 66 years (mean: 43 y). One case each arose in the kidney, ureter, perirenal soft tissue, and penis. All neoplasms demonstrated bland epithelioid to spindled cells set in a variably fibrous to fibromyxoid stroma, and only 1 had a peripheral shell of lamellar bone. All cases appeared well-circumscribed on gross/radiologic examination, though the primary renal neoplasm permeated between native renal tubules. By immunohistochemistry, S100 protein was negative in all 4 cases, while desmin was positive in 2 cases. In 2 cases, the Illumina TruSight RNA Fusion Panel demonstrated a PHF1::TFE3 and EP400::PHF1 fusion, respectively. In the remaining 2 cases, PHF1 gene rearrangement was confirmed by fluorescence in situ hybridization analysis. Due to unusual clinical presentation, lack of S100 positivity, and only occasional bone formation, the correct diagnosis was challenging in the absence of molecular testing. In summary, OFMT may rarely present primarily in the genitourinary tract. Given their nonspecific morphology and immunophenotype, molecular analysis is crucial to establish the correct diagnosis.
