• Explain to the patient that inflammation, blistering, or haematoma formation may occur

• Use freezing with care in children and on areas where the skin is thin, such as below the eyelids. In pigmented skin postinflammatory hyperpigmentation can occur

Bowen's disease

An intraepidermal carcinoma, if confirmed by incisional biopsy, can respond to repeated cryotherapy. Follow up is essential since progression to an invasive squamous carcinoma can occur.

Basal cell carcinoma

The superficial spreading type can be treated with liquid nitrogen, but repeated and often prolonged freezing is required.

This is not usually a routine procedure in general practice or hospital outpatients. Excision or radiotherapy are more effective methods of treatment.
