Cyst Removal

Skin cysts are common, fluid or keratin filled lumps that form beneath the skin’s surface. They are usually round, white or yellow in colour, and may feature a small dark opening called a punctum, from which keratin or pus can sometimes be released. While most cysts are harmless and non-cancerous, any cyst that becomes painful, swollen, or infected—or any new lump you're unsure about—should be examined by a dermatologist to rule out more serious conditions. Cysts are often categorised into types such as sebaceous, acne, or pilonidal cysts. Though few resolve on their own, persistent or bothersome cysts may require medical removal, especially if they impact your comfort or confidence.

Cysts can occur in anyone but are more common after puberty and in those with oily or acne-prone skin. They typically form when keratin becomes trapped beneath the skin, often due to blocked glands, trauma to hair follicles, or hormonal imbalances. Bacterial infections and genetic predisposition also play a role, particularly in pilar cysts, which are frequently found on the scalp and often run in families. Understanding the root cause can help prevent recurrence.

The most common types are epidermoid cysts, which usually appear on the face, chest, and shoulders and may leak a thick yellow substance, and pilar cysts, which develop on the scalp and tend to be firmer. Inflamed cysts can be painful, red, and swollen, resembling boils, while non-inflamed ones feel like smooth, mobile lumps under the skin. Epidermoid and pilar cyst removal (sebaceous cysts) is a simple procedure and is commonly performed at the Minor Surgery Clinic. If a cyst grows quickly, becomes tender, or starts oozing, it’s important to seek medical advice for proper diagnosis and treatment.
