What are Sebaceous Cysts?

A sebaceous cyst is a white or yellow bump under the skin. Sebaceous cysts can be found anywhere on the body, most commonly on the face, the neck, or the torso.

Sebaceous cysts occur when a sebaceous gland or its’ duct becomes blocked due to minor trauma. They contain a liquid or semi-liquid substance called sebum.

Cysts are typically harmless; however,  if they become infected, they may become larger, tender, and turn red.

Treatment of a sebaceous cyst may not be necessary because many heal on their own. If the cyst becomes large and tender, it may be necessary to have it drained by a medical professional. Never try to burst the cyst on your own as this may spread the infection and make it worse. A physician may have to prescribe an antibiotic and remove the cyst.

Methods of excising the cyst include:

  • Laser excision – performed with a laser
  • Minimal excision – minimal scarring
  • Punch excision – a small hole is created and the cyst removed
  • Wide excision – the whole cyst is removed and can leave a large scar.

If you think you have a cyst and it is not improving, do not diagnose it yourself. Seek professional care from a medical provider. If you would like to be seen by a physician at Flushing Hospital Medical Center, please call 718-670-5486.
