What is a Sebaceous Cyst?
A sebaceous cyst is a small closed ‘sac’ or cyst below the surface of the skin. It is generally filled with a white, semi-solid material called Sebum. The content of a sebaceous cyst is often likened to cottage cheese and it can often have an unpleasant odour.
Sebaceous cysts can be found almost anywhere on the body, more commonly they are found on the scalp, ears, back, face and torso. They are not normally found on the hands or soles of the feet.
What is the cause?
A sebaceous cyst can be caused by a trauma to the skin, a swollen hair follicle or high levels of testosterone in the body. Hereditary factors may also contribute to this condition.
What are the symptoms?
Sebaceous cysts are round in shape, smooth to touch and can vary in size.
Sebaceous cysts should not be painful, however, if they become infected they can become red, inflamed and painful to touch.
Sebaceous cysts do not go away by themselves and will only get bigger with time if left. Therefore, it is recommended that they are treated. The next page deals with the treatment options for sebaceous cysts.
