The main symptoms are a rash and irritation on the tip or shaft of the penis that persists. The area is most often red and does not respond to topical creams.
Exams and Tests
The health care provider will examine the penis to diagnose the condition and will perform a biopsy to make the diagnosis.
Treatment may include:
- Skin creams such as imiquimod or 5-fluorouracil. These creams are used for several weeks to months.
- Anti-inflammatory (steroid) creams.
If skin creams do not work, your provider may recommend other treatments such as:
- Mohs micrographic surgery or other surgical procedures to remove the area
- Laser surgery
- Freezing the cancer cells (cryotherapy)
- Scraping away cancer cells and using electricity to kill any that remain (curettage and electrodesiccation)
The prognosis for cure is excellent in most cases.
