Review
PURPOSE
Human papillomavirus (HPV) infection is the most common sexually transmitted disease, in males and females worldwide. While the role of HPV in female diseases is well known and largely studied, males have negligibly been included in these programs, also because the proportion of women suffering and dying from HPV-related diseases is much larger than men. The aim of this review is to focus on HPV-related diseases in male patients.
METHODS
We performed a literature analysis on the electronic database PubMed. We considered randomized trials, observational and retrospective studies, original articles having as topic the relationship between HPV male infection and the following items: oral, anal penile cancers, warts, condylomas, male infertility, altered sperm parameters, anti-sperm antibodies (ASA). We also included experimental in vitro studies focused on the effects of HPV infection on oocyte fertilization, blastocyst development, and trophoblastic cell invasiveness. In addition, studies describing the adjuvant administration of the HPV vaccination as a possible strategy to promote HPV clearance from semen in infected males were included.
RESULTS
Regarding head and neck HPV-related diseases, the most important non-neoplastic disease is recurrent respiratory papillomatosis (RRP). Regarding neoplastic diseases, the proportion of head and neck cancers attributable to HPV has increased dramatically worldwide. In addition, nowadays, it is thought that half of head and neck squamous cell carcinomas (HNSCCs) cases in the United States are caused by infection with high-risk HPV. HPV is noteworthy in andrological practice too. It was described as having a high HPV prevalence, ranging between 50 and 70%, in male penile shaft, glans penis/coronal sulcus, semen as well as in scrotal, perianal, and anal regions. Moreover, in male patients, HPV infection has been associated, among other diseases, with penile cancers. HPV semen infection has been reported in about 10% in men from the general population and about 16% in men with unexplained infertility, although these data seem widely underestimated according to clinical experience. In particular, HPV semen infection seems to be most related to asthenozoospermia and to anti-sperm antibodies (ASAs).
CONCLUSIONS
HPV infection represents a health problem with a detrimental social and public impact. Despite this evidence, little has been done to date to widely promote vaccination among young males.

BACKGROUND & OBJECTIVE
Penile squamous cell carcinoma (SCC) is an extremely rare malignancy. It is usually caused by chronic human papillomavirus (HPV) 16 and HPV 18 infections. This study was conducted to investigate the immunohistochemical overexpression of p16, a surrogate marker for HPV, and to evaluate its usefulness as a potential diagnostic biomarker.
METHODS
In this cross-sectional prospective and retrospective cohort study, 56 penile squamous cell carcinoma (SCC) specimens and five penile premalignant specimens were evaluated in Kasturba Medical College, Mangalore, India, from January 2013- December 2018 in terms of clinical and histopathological features. Immunohistochemical expression for p16 in cases and controls was evaluated. Statistical comparison of p16 expression among clinical features, histological subtype, grade, and stages of tumor were done.
RESULTS
Analysis of the pattern of p16 staining showed diffuse and strong nuclear and cytoplasmic expression in 32.8% of the cases. There was a highly significant association (<0.001) of pattern of p16 expression among the HPV and non-HPV subtypes of penile carcinoma. p16 expression was not significantly associated with other prognostic parameters like site of the lesion, lymphovascular invasion, perineural invasion, histologic grade, and pathologic stage.
CONCLUSION
Expression of p16 would be a useful tool in differentiation between the HPV-associated and non-HPV-associated subtypes of penile SCC that may be helpful in prediction of aggressiveness and invasive potential of the respective histologic subtypes.

OBJECTIVE
Lichen sclerosus (LS) is a chronic inflammatory skin disease. In male patients, it usually involves the glans penis and foreskin and can cause phimosis or meatal stenosis. The aim of this cross-sectional case-control study was to identify clinically important comorbidities in male patients with LS.
MATERIALS AND METHODS
By searching Turku University Hospital electronic health records, the authors identified 630 male patients diagnosed with LS between 2004 and 2020. To investigate possible comorbidities, the authors compared this patient group to a 10-fold larger control group.
RESULTS
The incidence of LS increased during the study period, from 5 to 27.5 per 100,000 men. Patients were most often diagnosed at 21 to 25 years of age. Patients with LS exhibited markedly increased risks of penile carcinoma (odds ratio [OR], 81.0; 95% CI = 10.82-3516.7; p < .001) and carcinoma in situ of the penis (OR = 60.5; 95% CI = 7.32-2738.9; p < .001). Patients also more commonly exhibited lichen planus (OR = 16.8; 95% CI = 8.97-32.39; p < .001), psoriasis (OR = 3.3; 95% CI = 1.80-5.70; p = .004), angina pectoris (OR = 1.8; 95% CI = 1.10-2.81; p = .013), obesity (OR = 2.6; 95% CI = 1.72-3.77; p < .001), type 2 diabetes (OR = 2.3; 95% CI = 1.74-3.09; p < .001), and hypertension (OR = 1.9; 95% CI = 1.53-2.37; p < .001). The most commonly performed urological procedures were operation for phimosis, uroflowmetry, and ultrasound measurement of residual urine.
CONCLUSIONS
Genital malignancies, other dermatological conditions, and diseases related to metabolic syndrome should be considered when treating patients with LS.

Review
Metastasis to the penis from renal cell carcinoma (RCC) or any other primary cancer site is unusual; when it does occur, it often involves multiple organs. A 75-year-old man presented with penile pain and swelling. Three months earlier, he had open radical nephrectomy with thrombectomy and was diagnosed with clear-cell RCC with tumor thrombosis in the inferior vena cava. The follow-up imaging indicated metastasis to the penis, prompting a total penectomy due to worsening pain. The excised mass displayed features consistent with metastatic RCC. This case underscores the need to consider rare metastatic sites, such as the metastasis of RCC to the penis, in RCC patients.

Penile malignancy is the third most common male-specific genitourinary malignancy, with squamous cell carcinoma representing the most common histologic type. Squamous cell carcinoma is an epithelial malignancy, frequently developing from the mucosal surfaces of the foreskin, glans, and coronal sulcus and manifesting as a distal infiltrative or ulcerated mass. This typically occurs in men from the 6th to 8th decades of life, and risk factors include human papillomavirus, phimosis, presence of foreskin and poor hygiene, chronic inflammatory conditions such as lichen sclerosus, trauma, and smoking. Primary urethral malignancies including urothelial carcinoma and adenocarcinoma can occur but may lack this distal predilection. Sarcoma, melanoma, leukemia or lymphoma, and metastatic disease are less common sources of penile malignancy. Because of the sensitive nature of penile malignancies, there may be delays in seeking care and in subsequent diagnosis. Recently, the staging guidelines for penile cancer have been updated concurrently with a shift toward more penile-preserving therapies, which have led to a larger role of imaging in diagnosis, staging, and treatment planning for penile malignancies. A variety of imaging modalities may play a role in the identification and staging of penile malignancy, including an increased use of MRI for local staging of tumors, CT and PET/CT for identification of nodal and distant disease, and US for image-guided biopsy. The authors discuss an imaging approach to a spectrum of penile malignancies, with an emphasis on radiologic and pathologic correlation and how knowledge of normal tissue types and anatomic structures can aid in the diagnosis and staging of these tumors.

Paget's disease was first described in 1874 as an eczematoid changes of the nipple associated with underlying breast carcinoma. Extra-mammary Paget's disease (EMPD) is rare with involvement of the male genitalia described in small case series and management options varying according to location and extent. The diagnosis of EMPD requires a high index of clinical suspicion and close liaison with the multidisciplinary team, particularly histopathology. We present two cases of EMPD affecting the male external genitalia that highlight important learnings in the presentation, diagnosis, and management of EMPD.

BACKGROUND
Carcinoma penis is more common in India compared to the West. The role of chemotherapy in carcinoma penis is ambiguous. We analyzed the profile and outcomes of patients with carcinoma penis treated with chemotherapy.
METHODS
We analyzed the details of all patients with carcinoma penis treated at our institute between 2012 and 2015. We collected particulars regarding demography, clinical presentation, treatment details, toxicities, and outcomes of these patients. Event-free and overall (OS) survival were calculated from the time of diagnosis until documentation of disease relapse/progression or death for the patients with advanced carcinoma penis who were eligible for chemotherapy.
RESULTS
There were 171 patients with carcinoma penis treated at our institute during the study period including 54 (31.6%) patients with stage I, 49 (28.7%) patients with stage II, 24 (14.0%) patients with stage III, 25 (14.6%) patients with stage IV, and 19 (11.1%) patients with recurrent disease at presentation. The present study included 68 patients with advanced carcinoma penis (stages III and IV) who were eligible for chemotherapy, with a median age of 55 years (range: 27-79 years). Sixteen patients received paclitaxel and carboplatin (PC) and 26 patients cisplatin and 5-FluoroUracil (CF). Neoadjuvant chemotherapy (NACT) was given to four patients with stage III and nine patients with stage IV disease. Of the 13 patients given NACT, we observed a partial response in five (38.5%), stable disease in two (15.4%), and progressive disease in five (38.5%) evaluable patients. Six (46%) patients underwent surgery after NACT. Only 28/54 (52%) patients received adjuvant chemotherapy. After a median follow-up of 17.2 months, the 2-year OS rates were 95.8, 89, 62.7, 51.9, and 28.6% for stages I, II, III, IV, and recurrent disease, respectively. The 2-year OS of patients who were given chemotherapy versus those who were not given chemotherapy were 52.7 and 63.2%, respectively (P = 0.762).
CONCLUSIONS
We report the real-world outcomes of two chemotherapeutic regimens used in consecutive patients with advanced carcinoma penis. Both PC and CF seemed effective and safe. However, approximately half of patients with advanced carcinoma penis do not receive the planned/indicated chemotherapy. We need further prospective trials regarding the sequencing, protocols and indications of chemotherapy in this malignancy.
