ABSTRACT
Introducción: Entre las lesiones malignas que se describen, se encuentra el cáncer de pene. Esta entidad constituye del 2 al 5 por ciento de los tumores urogenitales masculinos; la lesión metastásica es muy poco frecuente. Objetivos: Describir las características clínicas y evolución tórpida de un paciente con metástasis en el pene, de una neoplasia del colon. Caso clínico: Paciente de 54 años, antecedentes personales de salud, fumador, historia de hiperplasia prostática benigna y prostatitis crónica. Ingresa con dolor en hemiabdomen inferior y tumoración abdominal. Se diagnostica plastrón intraabdominal. Es intervenido quirúrgicamente; la biopsia de la lesión informa adenocarcinoma de colon. A los 7 días de evolución aparecen lesiones en el glande, que resultaron metástasis del adenocarcinoma de colon. Fallece por complicaciones de la enfermedad. Conclusiones: Las metástasis de las neoplasias del colon, en el pene, son infrecuentes; indican un estadio avanzado de la enfermedad, con un pronóstico desfavorable(AU)
Introduction: Among the malignant lesions described is penile cancer. This entity constitutes 2 percent to 5 percent of male urogenital tumors, and metastatic lesion is very rare. Objectives: To describe the clinical characteristics and torpid evolution of a patient with metastases in the penis from colon neoplasia. Clinical case: 54-year-old patient, personal health history. Smoker, history of benign prostatic hyperplasia and chronic prostatitis, which begins with pain in the lower abdomen and abdominal tumor, intra-abdominal plastron is diagnosed and is surgically intervened with a biopsy of the lesion that reports colon adenocarcinoma. At 7 days of evolution, lesions appeared on the glans that resulted in metastasis of colon adenocarcinoma. He dies from complications of the disease within six months. Conclusions: Colonic neoplasm metastases in the penis are infrequent, they indicate an advanced stage of the disease, with an unfavorable prognosis(AU)

ABSTRACT Purpose: To evaluate the erectile function in patients who underwent partial penectomy and identify factors associated with penile functional status. Materials and Methods: We identified patients who underwent partial penectomy due to penile cancer between 2009 and 2014. Clinical and pathological characteristics included patient age at the time of diagnosis, obesity, hypertension, dyslipidemia, diabetes, smoking, metabolic syndrome, Eastern Cooperative Oncology Group (ECOG) status, penile shaft length, tumor size, primary tumor stage (pT), clinical nodal status, and local recurrence. Erectile function was assessed prospectively with the International Index of Erectile Function (IIEF-5) at least 3 months after partial penectomy. Results: A total of 81 patients met analysis criteria. At the diagnosis, the median age was 62 years (range from 30 to 88). Median follow-up was 17 months (IQR 7-36). Of total patients, 37 (45%) had T2 or higher disease. Clinically positive nodes were present in 16 (20%) patients and seven (8.6%) developed local recurrence. Fifty patients (62%) had erectile dysfunction (ED) after partial penectomy, 30% had moderate or severe erectile dysfunction scores. Patients with ED versus without ED were similar in baseline characteristics except for age, penile shaft length, and presence of inguinal adenopathy (p <0.05). Multivariate analysis using logistic regression confirmed that older patients, shorter penile shaft length, and clinically positive lymph node were significantly associated with ED. Conclusion: Partial penectomy due to penile cancer provides adequate local control of the disease, however, proper counselling is important especially in relation to ED consequences. Preservation of penile length yields to more optimal erectile recovery.

Abstract: Objective: To determine external genital lesion (EGL) incidence -condyloma and penile intraepithelial neoplasia (PeIN)- and genital HPV-genotype progression to these EGLs. Materials and methods: Participants (healthy males 18-74y from Cuernavaca, Mexico, recruited 2005-2009, n=954) underwent a questionnaire, anogenital examination, and sample collection every six months; including excision biopsy on suspicious EGL with histological confirmation. Linear array assay PCR characterized 37 high/low-risk HPV-DNA types. EGL incidence and cumulative incidence were calculated, the latter with Kaplan-Meier. Results: EGL incidence was 1.84 (95%CI=1.42-2.39) per 100-person-years (py); 2.9% (95%CI=1.9-4.2) 12-month cumulative EGL. Highest EGL incidence was found in men 18-30 years: 1.99 (95%CI=1.22-3.25) per 100py. Seven subjects had PeIN I-III (four with HPV16). HPV11 most commonly progresses to condyloma (6-month cumulative incidence=44.4%, 95%CI=14.3-137.8). Subjects with high-risk sexual behavior had higher EGL incidence. Conclusion: In Mexico, anogenital HPV infection in men is high and can cause condyloma. Estimation of EGL magnitude and associated healthcare costs is necessary to assess the need for male anti-HPV vaccination.
Resumen: Objetivo: Determinar incidencia de lesiones genitales externas (LGE) -condiloma y neoplasia intraepitelial del pene (NIP)- y progresión de genotipos de VPH a LGE. Material y métodos: Se aplicaron cuestionarios, examen anogenital y recolección de muestras cada seis meses a hombres sanos (18-74 años, de Cuernavaca, México, reclutados 2005-2009, n=954) con biopsia y confirmación histológica. Se caracterizaron 37 tipos de ADN-VPH; se calculó incidencia de LGE (cumulativa con Kaplan-Meier). Resultados: Incidencia de LGE=1.84 (IC95%=1.42-2.39) por 100-persona-años (pa); 2.9% (IC95%=1.9-4.2) LGE acumulativa a 12 meses. Mayor incidencia de LGE entre hombres 18-30 años; 1.99 (IC95%=1.22-3.25) por 100pa. Siete sujetos tuvieron NIP I-III. VPH-11 más comúnmente progresa a condiloma (incidencia acumulativa a seis meses=44.4%, IC95%=14.3-137.8). Los sujetos con comportamiento sexual de alto riesgo tuvieron mayor incidencia de LGE. Conclusiones: En México la infección anogenital con VPH es alta y puede causar condiloma. La estimación de magnitud de LGE y los costos sanitarios asociados se necesita para evaluar la necesidad de vacunación contra VPH en hombres.

The present study aimed to investigate the relationship between histopathological subtype and the probability of inguinal lymph node metastasis (ILNM) in patients with penile squamous cell carcinoma (PSCC). The clinical records of 198 consecutive patients with PSCC were analyzed retrospectively. Primary lesions were reevaluated according to the 2016 World Health Organization (WHO) histopathological classification. We retrieved the clinicopathological factors from the medical records including age, clinical lymph node stage, pathological tumor stage, lymphatic invasion, and nerve invasion. Uni- and multivariate logistic regression analyses were used to explore the risk factors of ILNM. Multivariate analyses identified clinical lymph node stage (P = 0.000), pathological tumor stage (P = 0.016), histologic grade (P = 0.000), and risk group of histological subtypes (P = 0.029) as independent predictors for ILNM. Compared with the low-risk group of PSCC subtypes, the intermediate- (HR: 3.66, 95% CI: 1.30-10.37, P = 0.021) and high-risk groups (HR: 28.74, 95% CI: 2.37-348.54, P = 0.008) were significantly associated with ILNM. In conclusion, the histopathological subtype of the primary lesion is a significant predictor for ILNM in patients with PSCC.
