Initial Staging

Although relatively rare in the United States, penile squamous cell carcinoma is encountered worldwide at a higher rate. Initial diagnosis is often made on clinical exam, as almost all of these lesions are externally visible and amenable to biopsy. In distinction to other types of malignancies, penile cancer relies heavily on clinical nodal staging of the inguinal lymph node chains. As with all cancers, imaging plays a role in the initial staging, restaging, and surveillance of these patients. The aim of this manuscript is to highlight the applications, advantages, and limitations of different imaging modalities in the evaluation of penile cancer, including ultrasound, computed tomography, magnetic resonance imaging, and positron emission tomography.

Penile Squamous Cell Carcinoma

Background: Penile cancer is an aggressive and mutilating disease which deeply affects self-esteem and daily life of the patient. Penile cancer mostly affects the elderly, seen in people in their sixties and seventies. Occurrence in younger age is a need of research of penile neoplasia in young non-circumcised patients. Materials and Method: This is a three-year retrospective study. Data was extracted from the Department of Pathology and Medical Record section of B.P. Koirala Memorial Cancer Hospital. All histologically proven cases were included. The objective of this study was to assess clinical histopathological profile of penile carcinoma. Results. A total of 114 malignant cases were included out of which most common age group involved was 50-60 years with mean age of presentation being 51.6 years. Glans was the commonest site of involvement in 59 cases (51.7%). Well-differentiated squamous cell carcinoma was the most common type (71%). Forty nine patients (43%) presented when the mass size was 4-6 cm and 44 (39%) came with 2-4cm and rest less than 2 cm. Lymphvascular invasion was seen in 15 (13%) out of 114 cases and perineural invasion was seen only in 5 (4.3%) cases. 20 cases (17.5%) had lymphnodes positive which are less than 5 lymphnode positive and five (4.3%) had more than 5 lymphnodes positive. Conclusion. Early diagnosis and intervention of the patient ensure high probability of getting cured because the stage at presentation appears to be the most vital prognostic indicator for survival.

Penile Squamous Cell Carcinoma

Introduction Prognosis for patients with lymph node positive or metastatic penile squamous cell carcinoma remains poor. Chemotherapy with paclitaxel, ifosfamide, and cisplatin (TIP regimen) is recommended as a first-line option in this cohort of patients. No standard preferred subsequent-line therapy exists for patients with relapsed or refractory penile carcinoma following TIP chemotherapy. Molecular pathogenesis of penile cancer can be subdivided into human papilloma virus-dependent and human papilloma virus-independent pathways. Recent studies have demonstrated increased expression of programmed death ligand-1 in some penile tumors, commonly those that are human papilloma virus-negative. Given the rarity of penile carcinoma in industrialized countries and lack of effective therapies, checkpoint inhibitors may be an attractive treatment option for this subset of patients. Case report We report a case of metastatic penile cancer refractory to TIP chemotherapy, with a dramatic treatment response to ipilimumab and nivolumab. Molecular profiling of this tumor showed a high programmed death ligand-1 expression, high tumor mutational burden, high microsatellite instability, and alterations in DNA mismatch repair genes. Discussion This case highlights another dimension of information that may be gained with molecular genomic profiling of penile tumors, providing insight into the biologic behavior of this neoplasm and assessing for predictive biomarkers of response to immune checkpoint inhibitors.

Penile Squamous Cell Carcinoma

A 58-year-old Caucasian male presented to the urology clinic reporting an approximate one-year history of a persistent irritating, slowly progressive, glans penis redness. Biopsy revealed penile squamous cell carcinoma <em>in situ</em>. He underwent a partial glansectomy with circumcision and skin grafting. At three months follow-up there is no evidence of local disease recurrence. In western countries, primary malignant penile cancer is uncommon, with an incidence of less than 1 per 100,000 males. Squamous cell cancer accounts for more than 95% of cases of penile cancer. Squamous cell carcinoma <em>in situ</em> on the penile mucosa or transitional surfaces is also known as Erythroplasia of Queyrat. In the region, one third of penile squamous cell carcinoma <em>in situ </em>cases progress to invasive squamous cell carcinoma.

AbstractDifferentiation between penile squamous cell carcinoma patients who can benefit from limited organ-sparing surgery and those at significant risk of lymph node metastasis is based on histopathological prognostic factors including histological grade and tumor histological subtype. We examined levels of interobserver and intraobserver agreement in assessment of histological subtype and grade in 207 patients with penile squamous cell carcinoma. The cases were assessed by seven pathologists from three hospitals located in Sweden and Italy. There was poor to moderate concordance in assessing both histological subtype and grade, with Fleiss kappas of 0.25 (range: 0.02–0.48) and 0.23 (range: 0.07–0.55), respectively. When choosing HPV-associated and non-HPV-associated subtypes, interobserver concordance ranged from poor to good, with a Fleiss kappa value of 0.36 (range: 0.02–0.79). A re-review of the slides by two of the pathologists showed very good intraobserver concordance in assessing histological grade and subtype, with Cohen’s kappa values of 0.94 and 0.91 for grade and 0.95 and 0.84 for subtype. Low interobserver concordance could lead to undertreatment and overtreatment of many patients with penile cancer, and brings into question the utility of tumor histological subtype and tumor grade in determining patient treatment in pT1 tumors.

Abstract Background The choroid is the most common site for intraocular tumor metastasis because of its abundant vascular supply. However, choroidal metastasis in penile cancer is highly unusual. Here, we report the first case of diagnosis of choroidal metastasis at presentation in a patient with penile squamous cell carcinoma. Case presentation A 43-year-old Asian man with a 3-year history of penile cancer presented with metastasis in the right intraocular sites. Magnetic resonance imaging showed hyperintensity in the T1-weighted images and hypointensity in the T2-weighted images of the right eye. After enucleation of his right eye, histopathological analysis led to a diagnosis of metastatic, moderately differentiated penile squamous cell carcinoma. Conclusions Penile cancer typically occurs as penile squamous cell carcinoma, and its most common metastatic sites are the inguinal lymph nodes. Hemorrhagic transfer of tumor cells is extremely rare, especially to intraocular sites. Intraocular metastatic tumors have a unique presentation on imaging, as observed on magnetic resonance imaging and histopathological analysis. This novel finding of intraocular metastasis in penile squamous cell carcinoma is of great significance to optic surgeons and oncologists as it has new implications in the diagnosis of and timely intervention for penile cancer metastasis.
