Treatment for warts and skin lesions
Cryotherapy refers to a treatment in which surface skin lesions are frozen. A variety of skin lesions can be treated with cryotherapy including viral warts, seborrhoeic keratoses, sebaceous gland hyperplasia and dermatofibromas.
Dr Clayton undertakes cryotherapy in both of his private clinics using liquid nitogen. The fee for this procedure is £150.
Dr Clayton offers cryotherapy in all his clinics including his private consulting rooms on King Street in Manchester.
Dr Clayton’s brother Mr Philip Clayton FSSCh MBChA a fully UK trained podiatrist can also deliver this treatment at his private clinic in Cleveleys, Blackpool and also at Pall Mall Medical in Manchester. He can be contacted by clicking here.
Lesions that may treated by Dr Clayton with cryotherapy include:
Seborrhoeic keratoses (senile warts)
Specialist dermatologists sometimes freeze small skin cancers such as superficial basal cell and in situ squamous cell carcinomas (Bowen’s disease), but this is not always successful so careful follow-up is necessary.
Freezing may be the most suitable way of getting rid of many different kinds of surface skin lesion. It is relatively inexpensive, safe, and reliable. However, it is important that the skin lesion has been properly diagnosed.
Cryosurgery should never be used to treat melanoma or any undiagnosed pigmented lesion that could be melanoma. The following information video shows how it is undertaken in dermatology.
Cryotherapy using liquid nitrogen (temperature –196C) involves the use of a cryospray, cryoprobe or a cotton-tipped applicator. The nitrogen is applied to the skin lesion for a few seconds, depending on the desired diameter and depth of freeze. The treatment is repeated in some cases, once thawing has completed. This is known as a ‘double freeze-thaw’ and is usually reserved for skin cancers or resistant viral warts.
Freezes to -89C to a depth of 3mm
Looking after the treatment area
The treated area is likely to blister within a few hours. Sometimes the blister is clear and sometimes it is red or purple because of bleeding (this is harmless). Treatment near the eye may result in a puffy eyelid, especially the following morning, but the swelling settles within a few days. Within a few days a scab forms and the blister gradually dries up.
Usually no special attention is needed during the healing phase. The treated area may be gently washed once or twice daily, and should be kept clean. A dressing is optional, but is advisable if the affected area is subject to trauma or clothes rub on it.
When the blister dries to a scab, apply petroleum jelly (Vaseline) and avoid picking at it. The scab peels off after 5-10 days on the face and 3 weeks on the hand. A sore or scab may persist as long as 3 months on the lower leg because healing in this site is often slow.
Secondary infection is uncommon. When it occurs it may cause increased pain, swelling, thick yellow blister fluid, a purulent discharge and/or redness around the treated area. Consult your doctor if you are concerned: topical antiseptics and/or oral antibiotics may be necessary.
After a standard freeze of a solar keratosis, seborrhoeic keratosis or viral wart, the skin may appear entirely normal without any sign of the original skin lesion.
However, cryotherapy may result in a white mark (hypopigmentation) or a scar, particularly when freezing has been deep or prolonged, as is required for a cancerous lesion. A white mark may sometimes follow a light freeze. The white mark may be quite noticeable especially in those with darker complexions. Although the appearance often improves with time, the colour change can be permanent.
Skin lesions may fail to clear or may recur at a later date, necessitating further cryotherapy, surgery or other treatment.
A hard freeze to the skin overlying a superficial sensory nerve, such as treatment to a viral wart on the side of a finger, can cause numbness of the skin area that the nerve supplies. The feeling nearly always returns to normal within a few weeks or months.
