The scalp, like any other part of the skin, can develop infections or cysts that may lead to painful swelling and pus formation. In the image shown, a raised lesion with yellowish discharge is visible, suggesting the presence of an abscess or an infected cyst.
What Is a Scalp Abscess?
A scalp abscess is a collection of pus that forms beneath the skin due to a bacterial infection. It often appears as a red, swollen, and tender bump that may leak thick yellow or white pus. In some cases, the infection may originate from:
-
A sebaceous cyst that becomes inflamed or infected.
-
Folliculitis (infection of the hair follicle).
-
Injury or trauma to the scalp that allows bacteria to enter.
Causes of Scalp Infections
-
Bacterial Infection: The most common cause, usually due to Staphylococcus aureus.
-
Blocked oil glands: Sebaceous cysts can trap keratin and oil, becoming infected.
-
Poor scalp hygiene: Excess oil, dirt, and sweat can encourage bacterial growth.
-
Skin conditions: Dandruff, eczema, or psoriasis may increase susceptibility to infection.
Symptoms to Watch For
-
Painful, red, and swollen lump on the scalp
-
Pus or fluid discharge (often yellow or green)
-
Itching, burning, or tenderness around the area
-
Fever in severe cases
-
Foul odor if the infection is advanced
Treatment Options
-
Medical Drainage
-
Doctors may perform an incision and drainage to remove pus and relieve pressure.
-
-
Antibiotics
-
Oral or topical antibiotics help clear bacterial infections.
-
-
Warm Compresses
-
Applying a warm cloth can encourage natural drainage and reduce discomfort.
-
-
Surgical Removal of Cysts
-
In recurrent or chronic cases, cyst removal prevents repeated infections.
-
-
Proper Wound Care
-
Keeping the area clean and covered reduces the risk of reinfection.
-
Prevention Tips
-
Wash the scalp regularly to maintain hygiene.
-
Avoid scratching or squeezing bumps on the scalp.

Consult a dermatologist for recurring cysts or abscesses.
✅ Key Takeaway: A scalp abscess or infected cyst may look alarming but can be effectively treated with proper medical care. Early treatment helps prevent complications like spreading infections, scarring, or chronic recurrences.
