Electrodessication and curettage (ED&C) is a combined dermatological procedure used to treat various skin lesions, including precancerous growths, benign tumors, and certain types of skin cancers. This technique involves two main steps: electrodessication, which uses electric current to destroy abnormal tissue, and curettage, which involves scraping the surface of the lesion with a curette to remove any remaining diseased tissue. Electrodessication involves the application of a high-frequency electrical current to the lesion. This current generates heat, which dries out and destroys the abnormal tissue, effectively killing the cells and reducing blood flow to the area. The heat also helps to coagulate any bleeding vessels, minimizing bleeding during the procedure. Curettage is performed using a curette, a small, spoon-shaped instrument, to scrape away the top layers of the lesion and any remaining abnormal tissue. This step ensures the complete removal of the lesion and helps to prevent recurrence. The combination of electrodessication and curettage is effective for treating various types of skin lesions, including actinic keratosis (precancerous lesions caused by sun damage), basal cell carcinoma, squamous cell carcinoma, and certain benign growths such as seborrheic keratosis or warts. The primary causes for electrodessication and curettage include the need to treat abnormal skin growths or lesions that may be precancerous or cancerous, or to remove benign growths causing cosmetic concerns or discomfort. The procedure is particularly useful for lesions located on the skin's surface that can be easily accessed and where complete removal is necessary for effective treatment. Symptoms that may indicate the need for ED&C include the presence of a new or changing skin lesion, persistent sores or growths that do not heal, or abnormal skin changes that suggest a potential malignancy. The procedure is usually recommended when other less invasive treatments have been unsuccessful or when a more definitive treatment is required. Complications from electrodessication and curettage are relatively uncommon but can include infection, bleeding, scarring, and changes in skin pigmentation. Patients may experience temporary discomfort, swelling, and redness at the treatment site. Proper wound care and follow-up are essential to monitor healing and address any complications that may arise. After the procedure, patients are advised to keep the area clean and dry, avoid sun exposure, and follow any specific care instructions provided by their healthcare provider. ED&C is an effective method for treating and managing various skin lesions, offering both therapeutic and cosmetic benefits.
