Abstract
Squamous cell carcinomas with two or more coexisting clearly different histological subtypes of penile carcinomas are designated as mixed carcinomas in current classification models. They represent about 10% of all penile carcinomas. The aim of this study was to detect HPV genotypes in these unusual tumors. Tumors were selected from an international series of 1010 patients with penile carcinomas. Mixed carcinomas were grouped, according to WHO recommendations, as follows: 1. Carcinomas with warty/basaloid features mixed with HPV-independent carcinomas and 2. HPV-independent subtypes mixed with each other. HPV detection and p16INK4a immunostaining were performed. For HPV detection, whole tissue section-PCR analyses were performed by SPF10-DEIA-LiPA25 (version 1). As expected, HPV was detected more frequently in HPV-associated mixed carcinomas than in HPV-independent mixed carcinomas. Carcinomas with basaloid or warty features mixed with other SCC subtypes showed an HPV positivity rate of 46% (33 of 72 tumors) compared with 7% found in tumors with nonwarty/basaloid morphology (2 of 29 tumors). Eleven high-risk HPV genotypes were identified and the most common was HPV16 (65%) usually associated with basaloid morphology. p16INK4a immunostaining was positive in 76% of HPV-positive tumors. As in nonmixed carcinomas, although in lower proportion, a variable array of HPV genotypes was detected in mixed carcinomas. Apparently, the presence of a non-HPV component in an otherwise typical HPV-associated type tumor does adversely affect the prevalence of HPV positivity. Any amount of HPV-associated morphology superior to 20% in a mixed tumor is sufficient to classify them as HPV-associated, a WHO requirement.

Abstract
The landscape of squamous cell carcinoma of the penis (SCC-P) has undergone a significant transformation since the new World Health Organization classification of genitourinary cancers and recent European Association of Urology/American Association of Clinical Oncology guidelines. These changes emphasize the necessity to categorize SCC-P into 2 groups based on its association with human papillomavirus (HPV) infection. This shift has major implications, considering that prior knowledge was derived from a mix of both groups. Given the distinct prognosis, treatment options, and staging systems observed for HPV-associated tumors in other body areas, the question now arises: will similar patterns emerge for SCC-P?

Abstract
OBJECTIVES There is a paucity of data on North American cohorts of patients with penile squamous cell carcinoma (pSCC). Herein, we aimed to assess the sensitivity of various modalities to identify human papillomavirus (HPV) status, determine the prevalence of high-risk HPV-positivity, and evaluate the prognostic impact of relevant clinicopathologic variables. METHODS Patients with pSCC (n = 121) consecutively treated with partial/total penectomy (2000-2022) at a single institution were included. HPV status (based on immunohistochemistry [IHC], in situ hybridization [ISH], and panviral metagenomic sequencing [PMS]), histologic features, and outcomes were reviewed. Outcome events included death due to disease and progression. RESULTS The majority of patients were white (105/121, 86.8%). Thirty-seven (30.6%) were high-risk HPV-positive, and morphologic evaluation had a sensitivity of 97.3% (95% confidence interval [CI], 86.2-99.5) for predicting high-risk HPV status compared to IHC/ISH/PMS. Disease progression was more common among high-risk HPV-negative compared to high-risk HPV-positive patients (HR 2.74, CI 1.12-8.23, P = 0.03). Moreover, among high-risk HPV-negative patients, those with moderate-poorly differentiated tumors had increased disease-specific mortality (32.6%, CI 17.1-48.1) compared to those with well-differentiated tumors (0%). Among high-risk HPV-positive patients, those with basaloid morphology had lower disease-specific mortality (0% vs 14.4%, CI 0.0-33.1). CONCLUSIONS We demonstrate high-risk HPV-positivity in approximately one-third of patients with pSCC. Morphologic evaluation alone had a high sensitivity in correctly determining HPV status. Our results suggest that high-risk HPV status and morphologic features (differentiation in high-risk HPV-negative, and basaloid subtype in high-risk HPV-positive pSCC) may have prognostic value.

Abstract
Anogenital warts (AWs) represent a therapeutic challenge, especially in infants, due to sensitive skin and frequent disease recurrence. Though the initial wait-and-see approach is often adopted in asymptomatic immunocompetent children, with spontaneous clearing in almost 90% of cases within two years, persistent or symptomatic lesions can be reasonably treated. However, few studies have been conducted on children. Consequently, most treatments on patients under age 12 are not approved by the Food and Drug Administration. Herein, we review possible therapies for pediatric use in AW and report an illustrative case of a two-year-old boy with atopic skin and symptomatic, persistent AWs who was successfully treated with topical podophyllotoxin, without adverse effects or recurrence. Among available therapies for AWs, topical therapies, such as immunomodulating-agents (topical imiquimod 5% and 3.75% cream, sinecatechins 15% ointment) and cytotoxic agents (podophyllotoxin and cidofovir) are considered manageable in children because of their low aggressiveness. In particular, podofillotoxin gel 5% and imiquimod 5% cream have been reported to be safe and efficacious in children. Currently, HPV vaccination is not recommended as a treatment for established HPV infection and AWs, yet a possible therapeutic role of HPV vaccination was recently suggested in the literature and deserves mention.
