Atheroma Removal

Atheroma is a subcutaneous formation that’s easy to spot with the naked eye. What does atheroma look like? Visually, it usually has a round or oval shape with clear boundaries and protrudes slightly above the skin. When touched, atheroma is elastic, soft, and mobile under the skin—you can easily move it with your fingers.

Atheroma size varies from 0.5 cm to 5–7 cm, with cysts of 1–3 cm being most common. A typical sign is a small dark spot in the center, corresponding to the blocked sebaceous gland pore.

When pressed, atheroma may release thick whitish-yellow contents with a characteristic unpleasant odor. Self-squeezing is strictly prohibited, as it increases the risk of infection and complications.

In most cases, atheroma doesn’t hurt and causes no discomfort. The main problem is a cosmetic defect, especially if the cyst is located on the face, neck, or exposed areas of the body. Photos of atheroma help identify typical locations and sizes: cysts most often appear on the face, neck, back, and back of the head.

If atheroma starts to hurt, redden, increase in size, or swelling appears—these are signs of inflammation. In such cases, immediate medical consultation is needed to avoid complications and quickly remove the cyst without harming the skin. Often, infected atheroma looks like the photo below.

A common patient question—can atheroma go away on its own or disappear without treatment. The short and honest answer: no, atheroma doesn’t go away on its own. Even if it doesn’t change or bother you for a long time, it doesn’t mean the problem has disappeared. Why atheroma can’t resolve itself:

• The atheroma capsule is a formed connective tissue shell that doesn’t disappear without intervention.
• The cyst contents (keratin and sebum) have no exit due to the blocked duct.
• The body cannot independently eliminate such formations.

What happens to atheroma without treatment:

• It can remain unchanged for years, maintaining only a cosmetic defect.
• It may slowly increase in size due to content accumulation.
• It may become inflamed or infected, requiring urgent treatment.
• It may spontaneously rupture, but the capsule remains—and atheroma reappears after a few months.

Sometimes you can find advice about treating atheroma with ointments or anti-inflammatory agents. It’s important to understand—the effectiveness of conservative treatment is not proven. The only way to completely get rid of atheroma is surgical removal along with the capsule. If you remove only the contents, the recurrence risk is 80–90%.

Atheroma diagnosis is usually not difficult and in most cases doesn’t require lengthy or expensive examinations. An experienced dermatologist or surgeon can suspect atheroma during the initial examination, paying attention to the characteristic appearance of the formation, its typical location, and the presence of a central dark spot—the blocked sebaceous gland duct. This sign often helps distinguish atheroma from other subcutaneous growths.

During examination, the doctor necessarily performs palpation. They assess how mobile the formation is under the skin, what consistency it has, and whether it causes pain. In most cases, atheroma is soft or elastic, moves well, and doesn’t hurt if there’s no inflammation. If pain, redness, or swelling appears, this may indicate atheroma infection, which affects further treatment tactics.

To clarify the atheroma diagnosis and exclude other diseases, the doctor may order soft tissue ultrasound. Ultrasound examination allows visualization of a cystic formation with clear boundaries, presence of a capsule, depth of location, and connection with surrounding tissues. Ultrasound helps distinguish atheroma from lipoma, fibroma, enlarged lymph node, or other subcutaneous formations that may have a similar external appearance.

In some cases, the doctor may use dermatoscopy—examination of skin under magnification. This study is necessary to exclude malignant skin tumors, particularly melanoma, as some growths in early stages may look benign.

After atheroma removal, histological examination is mandatory. The removed formation is sent for pathomorphological analysis, which allows final confirmation of the atheroma diagnosis and exclusion of malignancy. Histology results are usually ready within 7–14 days. Biopsy as a separate diagnostic method is used rarely and only when there are doubts about the nature of the formation. Most often, atheroma is differentiated from the following conditions:

• Lipoma (fatty tumor), which is usually softer and has no central spot
• Fibroma, which is firmer and less mobile
• Hygroma in joint areas
• Lymphadenitis or dermoid cyst

Accurate atheroma diagnosis allows proper treatment method selection, timely removal of the formation, and minimizes complication risks, which is especially important for maintaining skin health and good cosmetic results.

Complications after atheroma removal occur quite rarely—statistically less than 5% of cases. However, every patient should know about possible risks to notice them in time and respond correctly. Among the most common complications:

• Atheroma recurrence. Most often occurs if the capsule wasn’t completely removed. In this case, atheroma may reappear in the same place after several months or even years. Treatment—repeat removal with complete capsule excision.
• Wound infection. May occur with improper post-operative care. Signs—pus, pronounced redness, pain, fever. Treatment includes antibiotics and wound debridement.
• Bleeding. Extremely rare complication that can occur with blood clotting disorders or taking anticoagulants. Requires bleeding control and wound revision if necessary.
• Keloid or hypertrophic scar. Tendency to form rough scars is more common in young patients and on body areas such as back or chest. For prevention, anti-scar ointments, silicone patches, and device therapy methods are used.
• Inflammation recurrence. May occur if the atheroma capsule wasn’t completely removed or infection remained.
• Temporary hardening. Sometimes after removal, hardening remains—this is normal, it usually resolves within 2–3 months.

To minimize complication risks, it’s important to choose an experienced surgeon and strictly follow all post-operative wound care recommendations. Timely response to any changes helps prevent serious problems and ensures good cosmetic results.
