Penile cancer

Summary of Penile cancer
Penile cancer is a malignant growth found on the skin or in the tissues of the penis. Around 95% of penile cancers are squamous cell carcinomas. Other types of penile cancer such as Merkel cell carcinoma, small cell carcinoma, melanoma and other are generally rare. Squamous cell carcinoma is more common in Asia, Africa, and South America. Precursor in situ lesions include: Bowen disease (in  penile shaft, presents as leukoplakia), erythroplasia of Queyrat (cancer of glans, presents as  erythroplakia), and Bowenoid papulosis (carcinoma in situ of unclear malignant potential, presenting  as reddish papules). Penile squamous cell carcinoma is associated with human papillomavirus infection and lack of circumcision.
