Drainage of superinfected cyst / furuncle – dermatologic surgical treatment

Drainage of a superinfected cyst or furuncle is a minor dermatological surgical procedure used for treatment of skin infections that cause pus accumulation at the skin level.

A superinfected cyst or a furuncle manifests through local inflammation, redness, pain, and formation of a purulent collection, which sometimes requires evacuation to promote healing.

The procedure consists of making a small incision at the site of the lesion and evacuating the purulent collection, followed by cleaning of the affected area. The intervention is performed under sterile conditions and usually with local anesthesia, for patient comfort.

Drainage is indicated for:

• skin furuncles or abscesses
• superinfected sebaceous cysts
• purulent collections localized at the skin level
• painful skin inflammations with pus accumulation

After the procedure, the physician provides recommendations regarding local care and necessary treatment, which may include topical or systemic treatment, depending on the severity of the infection.

The intervention contributes to reduction of inflammation, pain relief, and acceleration of the healing process.

The duration of the procedure is generally 10–20 minutes, depending on the size and location of the lesion.
