Sebaceous Cysts

The two most common forms of benign skin cysts are epidermoid cysts and pilar cysts. These are often collectively referred to as "sebaceous cysts" as they look and feel similar and are treated in similar ways. However, they are very different from other forms of cysts, such as ganglion cysts, which are made up of joint fluid.

Causes of Sebaceous Cysts

Epidermoid cysts are caused by some skin cells getting trapped under the skin. This can happen following a minor cut, from a blocked pore, or from body piercing.

Pilar cysts originate in the hair roots, and can happen spontaneously but are generally thought to be genetically inherited. Most pilar cysts occur on the scalp or other hair-bearing areas of the body.

Sebaceous cysts are benign and usually do not cause any discomfort or major functional limitation. They sometimes can drain spontaneously or become infected. If infected, often the cyst becomes suddenly more swollen, painful and red. The infection may be mild and resolve on its own or may be significant and require antibiotics and/or surgical drainage.

Treatment

If a cyst has no history of significant infection, and is not causing any major functional problem, then removal is not covered by the Medical Services Plan of BC and patients have to pay privately if they wish to have it removed.

Possible Complications: 

Surgery to remove a sebaceous cyst is done under local anesthetic in a minor surgery setting. Risks of the surgery can include bleeding, excessive scarring, recurrence (although rare), infection, anesthetic reaction, and wound healing complications.

A Message from PSG

As COVID-19 spreads across the country, our patients’ and our staffs’ health and welfare are our primary concern. To reduce the risk of spreading the virus we are implementing changes to reduce person to person contact. We may only be able to see urgent consults and follow ups. This applies to our offices as well as our clinics at the hospital. If appropriate, our staff may contact you to arrange a telephone appointment. As our senior population are at greatest risk, we will endeavour to reduce their exposure by deferring in person appointments unless absolutely necessary. Regrettably, there is a high likelihood your upcoming procedure or surgery may be deferred. If so, we will make every effort to rebook you as soon as the COVID-19 crisis resolves. We are closely following the guidance of the Ministry of Health and the Fraser Health Authority. We appreciate your patience and understanding.
