Sebaceous cyst









What is sebaceous cyst?

At the level of the skin next to the hair follicles (hairs) we find the sebaceous glands which are responsible for the secretion of sebum.

The sebaceous cyst is a benign formation that occurs by blocking the excretory duct of the sebaceous gland thus blocking the sebum and forming a collection under the skin.

The most common areas where sebaceous cyst occurs are the hair on the head, face, chest and back because there are more sebaceous glands.


The sebaceous cyst presents as a mobile tumor formation, of elastic consistency and variable size, located under the skin that grows slowly over time. The formation is initially painless but can become infected and then become inflamed and painful, and the skin above the formation becomes red and hot.

Sometimes the cyst can fistulate and then a foul-smelling whitish-gray discharge will appear.

Treatment of sebaceous cyst

Depending on the stage of the cyst, whether it is inflamed or not, it is recommended either its excision or drug treatment with anti-inflammatory and antibiotic until the regression of symptoms.

The appropriate treatment option will be decided after consultation with the specialist, after examination of the patient.

We recommend the early excision of the sebaceous cyst before its infection, the surgical treatment in the infected form being much more difficult, with a higher risk of recurrences and poorer aesthetic results.

What does surgery require?

The surgery is performed with local anesthesia and consists of excision of the entire cyst, both the membrane and its contents, to avoid the risk of recurrence, followed by washing with antiseptic solutions and suturing the skin.

The excised formation will then be sent to the anatomo-pathological examination to have a definite diagnosis.

Postoperative recommendations

• anti-inflammatory drugs and antibiotics will be administered as appropriate

• the sutures will be removed somewhere between 7 and 14 days depending on the area where the cyst is located

• postoperatively after the wound has healed, it is recommended to use creams and scars for scars and creams with protection factor 50+

• avoidance of local traumas

• the toilet of the area that was operated with betadine and saline
