Erythroplasia of Queyrat


Erythroplasia of Queyrat is an early form of skin cancer found on the penis. The cancer is called squamous cell carcinoma in situ.


The condition is most often seen in men who have not been circumcised. It is linked to the human papilloma virus (HPV).


The main symptoms are a red rash and irritation on the tip of the penis.


Your doctor or nurse will examine the penis. Treatment may include:

  • Skin creams such as imiquimod or 5-fluorouracil, which are used for several weeks to months
  • Anti-inflammatory (steroid) creams, if other medicines do not work

If skin creams do not work, your doctor may recommend mohs micrographic surgery or laser surgery.
