What is a Sebaceous Cyst?
Sebaceous cyst are very common lumps that develop underneath the skin. They are harmless in most cases, but can get infected and inflammed under certain conditions. Cyst removal surgery to remove the capsule and the cystic contents is curative. Punch excision is a excellent technique to remove the cyst leaving smaller scars and faster healing times.
OUR APPROACH
Sebaceous cyst
Sebaceous cysts, also known as epidermoid or keratin cysts, are non-cancerous bumps beneath the skin that result from blocked sebaceous glands. These cysts are typically slow-growing, painless, and can appear on various parts of the body, including the face, neck, and torso. While sebaceous cysts are generally harmless, many patients seek removal due to discomfort, potential for infection, or cosmetic concerns.
As a medical professional, we are dedicated to providing effective and safe treatments for the removal of sebaceous cysts. Our goal is to ensure patient comfort and achieve optimal aesthetic results.
How does a Sebaceous Cyst form?
The Sebaceous Cyst (aka epidermoid cyst, epidermoid inclusion cyst, infundibular cyst) is one the most common skin cyst seen in our daily practice. It commonly occurs on the face, scalp, body but can grow just about anywhere. Although twice in common in men, the sebaceous cyst tends to be more apparent as we get older. It is a harmless skin cyst, and does not have a risk of cancer transformation. Cyst removal surgery is the definitive way of removing the capsule and its contents completely.
The sebaceous cyst develops as the result of the elements of the epidermis (the top layer of the skin) growing within the dermis (the deeper layer of the skin). There are several reasons why a sebaceous cyst develops, but the exact mechanism remains unknown. Blocked pores, skin injury, infection and even sun exposure are cited a potential factors contributing to cyst formation.
You know that you have a sebaceous cyst when you feel a lump underneath your skin, and see an opening (technically called a punctum). This opening looks like a black dot, and you may even express cheesy smelly substance if you press onto your cyst. This is because the cyst is encased in a sac that is lined by skin cells actively producing macerated keratin (wet skin cells).

This is because the cyst is encased in a sac that is lined by skin cells actively producing macerated keratin (wet skin cells).
When infected, the skin overlying the skin can turn red, feel hot and tender. In later stages of infection, pus and blood may ooze out from the skin.
What is Steatocystoma Multiplex?
Steatocystoma Multiplex is considered a rare skin condition. In affected individuals, multiple cysts start appearing during the adolescent stage. While the condition may run in families, it may also occur out of nowhere. It is suspected that the condition arises due to a genetic mutation in a gene controlling certain skin elements.Â
The size of individual cysts in affected individuals with steatocystoma multiplex may range from 3mm to over 3cm. These skin cysts can number from a dozen to almost a hundred, and are commonly distributed on the face, chest, back and arms.
While this condition is benign, most individuals may prefer removal of some cyst in cosmetically apparent areas such as the face. A modified incisional technique to remove the cysts that we have developed leads to  better cosmetic effect, faster healing times and with minimal chance of recurrence. Learn more here.
Know when to seek Help
While most cyst can be left alone as it is harmless. On occasion the cyst may rupture or get inflammed resulting in pain, swelling, redness and even pus formation. When this happens, there is inflammation to the surrounding skin, and this causes great disomfort. You need to see a doctor when your cyst becomes painful because you may need treatment in the form of either oral antibiotics, or a surgical drainage if there is lots of pus.
Sebaceous Cyst Removal Surgery
As the sebaceous cyst resides deeper into the skin, lined by a sac of skin cells, taking antibiotics and regular pressing of the cyst contents are not curative. Cyst removal surgery is the preferred method to remove the cystic contents, the cystic sac and the overlying punctum. Most cyst removal surgery can be done under local anaesthesia. The overlying skin and cyst are carefully removed, ensuring that no fragments are left behind.
A minimal excision technique for cyst removal surgery makes use of an instrument known as a punch biopsy tool. The punch biopsy tool is entered into the skin over the opening of the cyst, and subsequently the cyst contents and cystic sac are then dissected out. This procedure gives a good cosmetic outcome, a smaller scar and faster healing time.
What does the cyst look like when it has been removed?
When an epidermal cyst is removed, it typically appears as a small, round, and encapsulated mass. Here are some details on its appearance and characteristics:
Shape and Size: The cyst is usually round or oval-shaped and can vary in size from a few millimeters to several centimeters in diameter, depending on how long it has been present and how much it has grown.
Capsule: The cyst is enclosed in a thin, fibrous capsule or sac. This capsule is made up of keratin and other cellular debris, which is produced by the epidermal cells lining the cyst.
Contents: When the cyst is opened, it contains a thick, pasty material that can be white, yellow, or cream-colored. This material is composed of keratin, a protein that forms the primary structure of hair, nails, and the outer layer of skin.
Consistency: The material inside the cyst can range from a cheese-like, semi-solid consistency to a more liquid, oily texture. It often has a distinctive, unpleasant odor.
Sebaceous Cyst Removal Surgery Options
- Excision Biopsy – Offers the best chance of removing the cyst wall and its contents. An incision is made onto the skin and the cyst is then removed. Specimen is sent for histological examination to confirm diagnosis and exclude malignancies.
- Punch Excision –Â A small surgical tool is inserted into the body of the cyst. The cystic contents and sac are removed through the small opening. The advantage is smaller number of sutures are needed and scars are smaller.
- Incision & Drainage – This is necessary when the cyst is infected and filled with pus. Healing of the infected tissues needs to take place before definitive treatment at a later date.
- Minimal Incision Surgery – A small incision is made to remove the cysts to avoid unsightly scars. This is only suitable for selected smaller cysts.Â

Cyst removal surgery
Cyst removal surgery is one of the most common procedures I undertake. When I examine an epidermal cyst for the first time, I want to check for signs of inflammation. Any redness, swelling, and pain may mean an underlying infection, and should be treated either with antibiotics or an Incision & Drainage procedure if pus is present.
