We Have to Know about the Sebaceous Cyst (Epidermoid Cysts)

  • Sebaceous cysts are small slow-growing painless lumps that arise within the skin on the face, upper back and upper chest
  • Sebaceous cysts are not cancerous

Causes of Sebaceous Cyst (Epidermoid Cysts)

  • The surface of skin (epidermis) is made up of a thin, protective layer of cells that body continuously sheds. Most epidermoid cysts form when these surface cells, instead of exfoliating normally, move deeper into skin and multiply
  • Most often, this occurs in areas where there are small hair follicles and larger sebaceous glands, such as face, neck, upper back and groin

Several factors can lead to this abnormal proliferation of cells, including:

  • Damage to a hair follicle by injuries such as abrasions or surgical wounds
  • A ruptured sebaceous gland. Sebaceous glands produce sebum, the oil that lubricates skin and coats each hair shaft. When these glands are ruptured by inflammatory skin conditions, especially acne, epidermoid cysts occur
