When it comes to skin conditions, few are as bothersome or as pungent as sebaceous cysts. These small, non-cancerous lumps can develop under the skin, and while often harmless, they can sometimes emit an unpleasant odor when they become infected or rupture. The smell, often described as cheesy or rancid, can be quite distinctive and embarrassing for those affected. Understanding what causes this odor and how to manage it is crucial for anyone dealing with sebaceous cysts.
Sebaceous cysts form when a sebaceous gland, which produces sebum to lubricate the skin and hair, becomes blocked. This blockage can lead to a buildup of sebum, dead skin cells, and other debris, resulting in a lump that can vary in size. While the cyst itself is usually harmless, if it becomes infected, it can lead to significant discomfort and a foul-smelling discharge. This is where the problem of sebaceous cyst stinks arises, often prompting individuals to seek medical advice or treatment.
In this comprehensive guide, we'll delve into everything you need to know about sebaceous cysts, including how they form, why they sometimes smell, and the best strategies for treatment and prevention. Whether you're currently dealing with a sebaceous cyst or simply want to be prepared in case one develops, this article will provide you with the information you need to manage the condition effectively and minimize any associated odors.

What Are Sebaceous Cysts?
Sebaceous cysts are small, slow-growing lumps that develop beneath the skin. These cysts are typically filled with a thick, oily substance called sebum, which is produced by the sebaceous glands. The primary function of these glands is to keep the skin and hair moisturized. However, when a gland becomes blocked, a cyst can form.
These cysts are most commonly found on the face, neck, and torso, but they can occur anywhere on the body where sebaceous glands are present. They are generally non-cancerous and painless unless they become infected.
It's important to note that while sebaceous cysts are common, they can vary significantly in size and may sometimes be mistaken for other types of skin lumps. Proper diagnosis by a healthcare professional is essential for appropriate treatment.
Types of Sebaceous Cysts
There are primarily two types of sebaceous cysts:
- Epidermoid Cysts: These are the most common type and are often referred to as sebaceous cysts. They originate from the epidermis, the outer layer of skin.
- Pilar Cysts: Also known as trichilemmal cysts, these develop from hair follicles and are typically found on the scalp.
Causes of Sebaceous Cysts
Sebaceous cysts can form due to various reasons, including:
- Blocked Sebaceous Glands: The most common cause is a blocked gland, which can lead to an accumulation of sebum.
- Follicle Damage: Injury to a hair follicle can result in the development of a cyst.
- Skin Conditions: Certain skin conditions like acne can increase the likelihood of cyst formation.
- Genetic Factors: Some individuals may be genetically predisposed to developing sebaceous cysts.
Why Do Sebaceous Cysts Stink?
The unpleasant odor associated with sebaceous cysts is often due to infection. When a cyst becomes infected, bacteria begin to break down the sebum and other debris inside the cyst, resulting in a foul-smelling discharge. This discharge can be quite distressing and may require medical treatment to resolve.

In addition to infection, the smell can also be caused by the natural breakdown of keratin, a protein found in skin cells. As the cyst fills with dead skin cells and sebum, the keratin can begin to decompose, producing a distinct odor.
How to Identify an Infected Cyst?
An infected sebaceous cyst may exhibit several noticeable symptoms, including:
- Redness and swelling around the cyst
- Increased pain or tenderness
- Warmth in the area surrounding the cyst
- Foul-smelling discharge
- Fever (in severe cases)
What Should You Do If a Cyst Smells?
If a sebaceous cyst begins to emit a bad odor, it's important to seek medical advice. A healthcare professional can determine whether the cyst is infected and recommend appropriate treatment options. Treatment may include:
- Antibiotics to combat infection
- Incision and drainage to remove pus
- Surgical removal if the cyst is recurrent or problematic
Symptoms of Sebaceous Cysts
Sebaceous cysts are generally easy to identify due to their distinct characteristics. Common symptoms include:
- A small, round lump under the skin
- Skin-colored or slightly yellowish appearance
- Soft to the touch
- Painless unless infected
Do Sebaceous Cysts Grow Over Time?
While sebaceous cysts typically grow slowly, they can become larger over time. In some cases, they may remain stable in size without causing any issues. However, if a cyst grows rapidly or becomes painful, it may indicate an underlying problem such as infection.
Can Sebaceous Cysts Cause Other Symptoms?
In rare cases, sebaceous cysts may lead to additional symptoms if they become infected or rupture. These symptoms can include:
- Drainage of a thick, yellowish fluid
- Unpleasant odor
- Discomfort or pain
How Are Sebaceous Cysts Diagnosed?
Diagnosing a sebaceous cyst typically involves a physical examination by a healthcare provider. During the examination, the provider will assess the size, shape, and location of the cyst. In some cases, they may use imaging tests such as an ultrasound or CT scan to confirm the diagnosis and rule out other conditions.
Do You Need a Biopsy for a Sebaceous Cyst?
In most cases, a biopsy is not necessary for diagnosing a sebaceous cyst. However, if the provider suspects that the lump may be something more serious, they may recommend a biopsy to ensure an accurate diagnosis.
What Tests Can Help Identify Sebaceous Cysts?
Aside from a physical examination, other tests that may help in diagnosing sebaceous cysts include:
- Ultrasound: This imaging test can help visualize the structure of the cyst.
- CT Scan: A CT scan may be used if the cyst is large or located in a sensitive area.
Treatment Options for Sebaceous Cysts
Treating sebaceous cysts depends on their size, location, and whether they are causing symptoms. Some common treatment options include:
Can Sebaceous Cysts Go Away on Their Own?
In some cases, sebaceous cysts may resolve on their own without treatment. This is more likely if the cyst is small and not causing any discomfort. However, if a cyst is painful, infected, or growing, medical intervention may be necessary.
What Are the Medical Treatments for Sebaceous Cysts?
Medical treatment for sebaceous cysts may involve:
- Incision and Drainage: A healthcare provider may drain the cyst if it is infected or causing discomfort.
- Antibiotics: If the cyst is infected, antibiotics may be prescribed to eliminate the infection.
- Surgical Removal: For recurrent or problematic cysts, surgical removal may be recommended to prevent future issues.
Can You Prevent Sebaceous Cysts?
While it's not always possible to prevent sebaceous cysts, there are steps you can take to reduce your risk of developing them. These include:
What Lifestyle Changes Can Help Prevent Cysts?
Adopting certain lifestyle changes can help minimize the likelihood of sebaceous cyst formation:
- Maintain a regular skincare routine to keep pores clear
- Avoid squeezing or picking at pimples and spots
- Use non-comedogenic skincare products that don't clog pores
- Practice good hygiene, especially in areas prone to sweating
Are There Any Dietary Changes That Can Help?
While there's no specific diet to prevent sebaceous cysts, a balanced diet rich in fruits, vegetables, and whole grains can support overall skin health. Staying hydrated and limiting the intake of greasy or fatty foods may also be beneficial.
Home Remedies to Reduce Cyst Odor
For those dealing with the unpleasant smell of a sebaceous cyst, some home remedies may help alleviate the odor. These remedies are not a substitute for medical treatment but can be used alongside professional care.
How Can Warm Compresses Help?
Applying a warm compress to the cyst can help reduce inflammation and promote drainage. This may help minimize odor by allowing the cyst to empty more effectively.
What Role Does Tea Tree Oil Play?
Tea tree oil has natural antibacterial properties and may help reduce odor by killing bacteria around the cyst. Dilute the oil with a carrier oil before applying it to the skin to avoid irritation.
When Should You See a Doctor?
While sebaceous cysts are generally harmless, there are certain situations where medical attention is necessary:
