How We Diagnose Skin Cysts
Seborrhoeic keratoses (SKs), sometimes historically referred to as seborrhoeic warts or basal cell papillomas, are very common, benign (non-cancerous) skin growths. They often appear with age and are caused by a buildup of keratin, a natural protein found in the skin.
These growths are harmless and non-contagious, but they can become uncomfortable or cosmetically bothersome.
Common features of seborrhoeic keratoses
- Usually appear after age 40
- Can be light tan, brown, or black in colour
- Often look waxy, rough, or βstuck onβ
- May feel slightly raised, bumpy, or scaly
- Commonly found on the face, scalp, back, chest, or shoulders
- May appear alone or in clusters
Although SKs are not dangerous, they can sometimes resemble moles or even skin cancers like melanoma. A professional diagnosis is essential to ensure a correct identification and appropriate management plan.
Causes & Risk Factors
While the exact cause is unknown, several factors contribute to SK development:
- Age Most common in individuals over 40
- Genetics Can run in families
- Sun exposure May play a role in triggering lesions
- Skin type More common in lighter skin tones
You may have just one lesion or dozens. Some people develop them rapidly in clusters.
How We Diagnose Seborrhoeic Keratoses
Our GMC-certified dermatologists will perform a thorough physical examination. SKs can usually be diagnosed visually due to their characteristic appearance. We will use a dermatoscope to get a close look at the growth and rule out other, more serious conditions like melanoma. This ensures an accurate and safe approach before any treatment begins.

Seborrhoeic Keratoses Removal Methods
one of the following clinically approved methods:
- Cryotherapy This highly effective procedure uses liquid nitrogen to freeze the growth. The seborrhoeic keratosis will then blister and fall off, typically within a few weeks. It is a quick and non-invasive treatment that leaves minimal scarring.
- Shave Excision For larger or thicker SKs, a shave excision may be used. The dermatologist uses a fine surgical blade to shave the growth off, leaving a flat, smooth surface. The wound is then cauterised to stop bleeding. This is a very effective method that leaves a minimal scar.
- Curettage This involves using a small, spoon-shaped instrument (a curette) to scrape the growth from the skin. It is often combined with cauterisation for a complete excision.
- Electrosurgery (Optional) Sometimes used alongside curettage to seal the area and reduce recurrence.
All treatments are performed under sterile conditions with minimal discomfort and downtime.

Frequently Asked Questions about Seborrhoeic Keratoses
No, seborrhoeic keratoses are benign (non-cancerous) and not contagious. However, because they can sometimes resemble skin cancers like melanoma, itβs important to get any new or changing growth checked by a dermatologist.
Most patients experience minimal discomfort. For cryotherapy, you may feel a brief cold or stinging sensation. For procedures like curettage or shave excision, a local anaesthetic is used to numb the area so you wonβt feel pain during treatment.
Cryotherapy usually takes just a few minutes per lesion. Curettage or shave excision may take 15β30 minutes, depending on the size and number of growths being treated.
Once an SK is fully removed, it typically wonβt return in the same spot. However, new lesions may develop in other areas over time, especially as we age.
Yes. In many cases, several lesions can be treated in a single session, depending on their size and location.
Seborrhoeic keratoses often look waxy, raised, and βstuck-on,β while moles tend to be flatter and more uniform. A dermatologist uses a dermatoscope to accurately distinguish between them.
Home remedies or over-the-counter treatments are not effective and can damage your skin. Professional removal ensures safety, accuracy, and minimal scarring.
Because seborrhoeic keratoses are harmless, their removal is typically considered cosmetic and is not covered by the NHS or most private insurers. We provide transparent pricing at your consultation.
