Penile cysts are uncommon lesions. In general, they are asymptomatic and do not interfere with sexual function. Most of them are present since birth, but usually they are only detectable in adolescence or adulthood. We report a rare case of a young adult man with a 5 × 5-cm nodule on the prepuce (ventral face), which appeared 2 years ago and interfered with his sexual function. The nodule was excised by circumcision and a histopathologic study was performed. Histopathologic examination revealed a mucoid cyst of penis with epidermoid metaplasia. No recurrence was observed at a 6 months follow-up and the patient's sexual function returned to normal.Can Urol Assoc J 2010;4(6):E155-E157

Objective: To evaluate the epidemiological factors associated to medical circumcision, based on data from the Brazilian public health system. Methods: Using the Unified Health System public database between 1984 and 2010, hospital admissions associated with surgical treatment of phimosis were searched. A total of 668,818 men admitted to public hospitals who underwent circumcision were identified and included in the present study. Results: A mean±standard deviation of 47.8±13.4 circumcisions/100,000 men/year was performed through the Unified Health System for medical reasons. During the 27-year period evaluated, 1.3% of the male population required circumcision for medical reasons. Total number of circumcisions and circumcision rate increased in childhood, declined progressively after 5 years of age and rose again progressively after the sixth decade of life. In the regions of the country with better access to healthcare, 5.8% of boys aged 1 to 9 years old required circumcisions. From 1992 to 2010 there were 63 deaths associated with circumcisions (mortality rate of 0.013%). Conclusion: In conclusion, yearly circumcision rates could be estimated in Brazil, and a very low mortality rate was associated with this procedures. Circumcision is mostly performed in children in the first decade of life and a second peak of incidence of penile foreskin diseases occurs after the sixth decade of life, when circumcision is progressively performed again.
