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 papillomavirus (HPV).
The main symptoms are a red rash and irritation on the tip or shaft of the penis that do not go away.
Exams and Tests
Your health care provider will examine your penis and may do a biopsy to diagnose the condition.
Treatment may include:
- Special skin creams that 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 other treatments, such as:
- Mohs micrographic surgery
- Laser surgery
- Freezing the cancer cells (cryotherapy)
- Scraping away cancer cells and using electricity to kill any that remain (curettage and electrodesiccation)
