Earlobe cysts, or epidermoid cysts, look like small, smooth bumps under the skin of the earlobe. They can vary slightly in colour, from matching your natural skin pigmentation through to a bright red.
They are generally no bigger than the size of a pea, but you should pay attention to any changes in size as this might be a sign that you should seek medical advice.
If a cyst bursts or is damaged, it might leak a thick, white fluid called keratin.
Cysts in the earlobe are almost always benign and shouldn’t cause any problems other than a minor cosmetic issue. Sometimes an earlobe cyst can become infected and will then require medical attention. Signs of an infection may include:
redness and inflammation of the area
swelling and tenderness or pain
a boil-like infection from a burst cyst
