Cryosurgery utilizes application of extreme cold (liquid nitrogen) to destroy abnormal tissue. It is used to treat benign or pre-cancerous skin lesions, including actinic keratoses, solar lentigines, skin tags, seborrheic keratosis, and viral warts.
A skin biopsy is a biopsy technique used to remove a skin lesion. The biopsied lesion is then evaluated by a dermatopathologist who renders a microscopic diagnosis. Skin biopsies are used by a dermatologist to diagnose or rule out certain skin conditions or diseases, including skin cancers. There are 3 types of skin biopsies:
Excisional surgery is similar to an excisional biopsy, but is completed on a lesion that has already been diagnosed as malignant, such as a squamous cell carcinoma or a melanoma. In an excisional surgery, the lesion is removed by the dermatologist with a scalpel. The entire lesion and a small portion of surrounding normal skin is removed to insure that there are clear margins (all surrounding tissue is malignancy free).
Electrodesiccation and Curettage is a surgical procedure where a dermatologist removes a skin lesion (typically skin cancers such as squamous cell carcinoma and basal cell carcinoma) by scraping the lesion with a curette (a long, thin surgical instrument with a sharp curved edge) and then treating the area with an electric needle (electrode) to destroy any remaining cells.
Mohs Micrographic surgery is a specialized, methodical surgical technique for the removal of certain skin cancers. Mohs surgery is performed in stages and offers the immediate and complete microscopic examination of removed cancerous tissues, so that all extensions of the cancer can be eliminated. Due to the methodical manner in which tissue is removed and examined, Mohs surgery is the skin cancer treatment with highest reported cure rate. Dr. Sigrid Barklund is the Mohs surgeon for Dermatology & Laser Associates of Medford, LLP.
Photodynamic Therapy is a skin treatment for Actinic Keratoses (AK’S) or acne. PDT is performed by a Certified Technician.
UVB Phototherapy is utilized to treat psoriasis, vitiligo, and other skin conditions through exposure to narrow-band UVB lights. Patients apply a thin layer of tar or petrolatum to the affected areas of the skin and enter the UVB light box for a prescribed treatment time. Treatments are typically prescribed for 2-3 sessions weekly. After prescription from a dermatologist for UVB Phototherapy, this treatment is provided on a walk-in basis in Suite B at Dermatology & Laser Associates of Medford, LLP.
