9 in 10 people with BHD get pale skin bumps. These can be on their face, ears, neck and upper body. These skin bumps are non-cancerous skin tumours. They are not dangerous, but can cause some people to feel anxious or self-conscious.

People with BHD can get several different types of skin lesion, but the most common are fibrofolliculomas.

There are several different types of skin lesion, which can be caused by different diseases. It is important that you see a dermatologist who will be able to tell you exactly what type (or types) of skin lesion you have.

If your dermatologist tells you that you have fibrofolliculomas, trichodiscomas or acrochordons, it is possible that you may have BHD syndrome. If this happens, it is very important to get a genetic test because BHD syndrome also puts you at risk of developing a collapsed lung and kidney tumours. Skin symptoms are often the first symptom that BHD patients notice, so getting a correct diagnosis before lung or kidney symptoms develop is important.
