Symptoms of Epidermoid Cysts

In general, epidermoid cysts are round in appearance. A dark portion of the cyst is visible on the skin. If the cyst becomes infected, it will be red and tender. When a cyst is squeezed, it can produce a cheesy white discharge.

Treatment of Epidermoid Cysts:

  • Effective treatment of epidermoid cysts requires the sac of the cyst be completely removed. If the cyst is squeezed and the discharge is forced out, the cyst will reappear in the skin.
  • Usually, a doctor will be able to remove the cyst by making a small incision in the skin.
  • Antibiotics may be prescribed to treat infected cysts.
