I have some large rough patches of skin on my foreskin which over the past year have been slowly spreading. There is no pain or discomfort associated with them, however they make the skin quite thick in the area and it is making my foreskin uncomfortably tight, to the point where I can't retract it when I have an erection anymore. What is this? Who do I see about it?

Thank you.

Answer
You most likely have a skin condition called lichen planus.
The cause of lichen planus is unknown, though strong evidence suggests that inflammation, controlled by the immune system, gives rise to the lesions. However, certain diseases, medical conditions or other factors may act as triggers of lichen planus in some people.

The possible triggers of lichen planus include:

Hepatitis C infection
Hepatitis B vaccine
Flu vaccine
Certain pigments, chemicals and metals
Nonsteroidal anti-inflammatory drugs, such as ibuprofen (Advil, Motrin IB, others) and naproxen (Aleve, others)
Certain medications for heart disease, high blood pressure or arthritis
See your dermatologist for treatment.
