Medical Care

Stucco keratosis is a benign lesion that can be removed by curettage or cryotherapy.

Different methods or a combination of methods can be used to remove the stucco keratosis lesions. The most common methods in practice are liquid nitrogen therapy and curettage.

Liquid nitrogen therapy in stucco keratosis

Lesions can be frozen with liquid nitrogen by either the spray method or the dipstick method. Because the lesions are benign, the required temperature of the lesion should reach -25°C.

Depending on the thickness of the lesion, two freeze cycles of 3-10 seconds are usually required. The lesions fall off in a few days, and, if the procedure is not successful, liquid nitrogen therapy may be repeated. Ambient temperature and skin temperature, as well as underlying vascularity, must be taken into account. Ulceration can occur if cryotherapy is too vigorous.

Curettage in stucco keratosis

Stucco keratosis can be removed by curettage. Lesions can be removed by gentle scraping. Once the lesion is removed, topical petrolatum can be applied.

Other methods used in stucco keratosis

The lesion can be removed by using an electrodesiccator.

Shave removal is performed only if the lesion appears malignant, does not respond to cryotherapy and/or curettage, or requires a definitive diagnosis.


Surgical Care

No surgical care is required in stucco keratosis.


Long-Term Monitoring

Patients with stucco keratosis should be advised to have a periodic skin examination.
