Epidermoid Cysts


What is an Epidermoid Cyst?

Epidermoid cysts are small, hard lumps that are found under the surface of the skin. These cysts are common among people and grow at a slow rate. However, these are rarely ever cancerous. They may be tan or yellow in color because of the thick, smelly pus that it contains. It usually occurs on the face, neck, back, genitals, etc. Their size ranges from ¼ inch – 2 inch in diameter. Due to their benign nature, people may ignore them unless they cause pain, swelling

and difficulty in daily life. People also refer to them as sebaceous, keratin or epithelial cysts, but they are different, sebaceous cysts arise from sebaceous glands that secrete oily matter that moisturizes the hair and the skin.

Epidermoid Cyst Causes

  • Skin trauma: When there is a lesion or injury on the surface of the skin due to any incident, an epidermoid cyst may occur. The affected area may collect dirt, skin and other material that gives way to the formation of the cysts.
  • Keratin build-up: Keratin is a material that is naturally present in the skin and hair. However, if this substance accumulates under the skin it may develop into an epidermoid cyst.
  • Hair break: Sudden break of hair and uprooting of the hair follicle can also lead to the growth of a cyst. When the hollow of the hair follicle is left empty, oil and dirt may accumulate into it and cause an infection. This may cause redness, swelling and pain.
  • HPV infection: This kind of infection occurs when the virus enters the body through a cut or abrasion or by skin to skin contact. It can also be transferred sexually.
  • Sunburn: Exposure to the sun for a long time can damage skin cells. On top of that, the harmful ultraviolet rays of the sun must be avoided to prevent the occurrence of such cysts.
  • Genetics: Some individuals are likely to develop epidermoid cysts because of their genes. Their body produces more of the oily substances that accumulate to form the cysts.

Complications

  • Infection: Cysts may lead to an infection after they develop. The infection may also create an abscess that can be painful.

The doctor can remove the entire cyst and ask the patients to revisit again to remove the stitches. However, the doctors may postpone the removal procedure if there is inflammation of the cyst.
  • Injection: The method involves injecting the cyst with a medicine. This medicine is useful as it helps to reduce the swelling and pain that an individual experiences due to the cyst.
