What is it?
Sebaceous cysts are less common. They arise from the glands that secrete oily matter that lubricates hair and skin (sebaceous glands).
What are the symptoms?
Sebaceous cyst signs and symptoms include:
- A small, round lump under the skin, usually on the face, neck or trunk
- A tiny blackhead plugging the central opening of the cyst
- A thick, yellow, smelly material that sometimes drains from the cyst
- Redness, swelling and tenderness in the area, if inflamed or infected
- Placing a warm, moist cloth over the area to help the cyst drain and heal
- Not squeezing a cyst yourself
Things to watch out for
Cysts are sometimes confused with boils or skin abscesses. GP should be contacted for proper diagnosis
