Cryotherapy is the use of liquid nitrogen to destroy specific types of skin lesions. This therapy is most commonly used on actinic keratoses, which are precancerous lesions, or seborrheic keratoses, which are benign skin growths. Application of liquid nitrogen to these lesions causes the skin to blister and peel off. Once the lesions have peeled off, new skin can grow.

Skin Allergy Testing

Advanced Practice Dermatology uses the noninvasive T.R.U.E. skin patch test. The T.R.U.E. TEST is an epicutaneous patch test indicated for use to aid in diagnosing allergic contact dermatitis in persons six years of age and older whose history suggests sensitivity to one or more of the 36 substances included on the T.R.U.E. TEST panels.

Skin Cancer Screening

Skin cancer screenings are critical in identifying precancerous and cancerous lesions of the skin. Many times skin cancers are not obvious or bothersome and can grow without distinctive symptoms. Skin cancer screenings help to identify these lesions and help to identify risk factors associated with skin cancer.

Skin cancer screenings include visual and physical evaluation of moles, skin lesions, and areas of the skin for atypia. If suspicious lesions are identified, they may be biopsied by your provider. If the lesions are cancerous, further surgery or referral for Mohs surgery may be necessary.


All providers at Advanced Practice Dermatology perform surgical procedures to remove moles and certain types of skin cancers. If Mohs surgery is required (a specific type of skin cancer removal surgery), we refer to local and statewide Mohs surgeons.
