Cryotherapy: Minimally Invasive Skin Lesion Removal
Cryotherapy is a minimally invasive method for removing skin lesions by destroying abnormal tissues using extremely cold liquids and specialized instruments.
The most commonly used agent is liquid nitrous oxide, though carbon dioxide snow, dimethyl ether, or propane-based agents may also be used.
Benefits of Cryotherapy:
-
Low cost
-
Fast procedure
-
Simple to perform
-
Safe for most patients
-
Few potential complications
Common Indications for Cryotherapy:
Cryotherapy is most often used to treat benign skin conditions and remove growths such as:
-
Actinic keratosis
-
Seborrheic keratosis
-
Viral warts
-
Molluscum contagiosum
-
Various soft benign skin lesions
Occasional Oncological Use:
In select cases, cryotherapy can also be used to treat early-stage cancerous changes, including:
-
Superficial basal cell carcinoma
-
In-situ squamous cell carcinoma (e.g., lesions on the legs)
However, these cases require closer follow-up and attentive skin monitoring after treatment.
When Cryotherapy is Not Recommended:
Cryotherapy is contraindicated in the following cases:
-
Unclear diagnosis of the lesion
-
Suspected or confirmed melanoma
-
Patients with darker skin tones (due to pigmentation risks)
-
Lesions requiring histological examination
-
History of adverse reactions to cryotherapy
-
Young children
-
Unconscious patients
-
Underlying conditions triggered by cold exposure
