Histopathological analysis of the therapeutic response to cryotherapy with liquid nitrogen in patients with multiple actinic keratosis

Abstract: Actinic keratoses are premalignant lesions of the skin caused by excessive sun exposure. Lesions may become mainly squamous cell carcinoma. Cryotherapy with liquid nitrogen is one of the main treatments. In order to evaluate the response of actinic keratosis to cryotherapy by histopathology, two lesions were selected in each of 14 patients with multiple actinic keratoses. In one lesion a biopsy was performed and in the other lesion a biopsy was performed after cryotherapy. Subsequently, both biopsies were comp… Show more

“…In many cases, AKs are subclinical and disseminated; therefore, the term field cancerization is nowadays more appropriate to describe the lesions . Though it has no mortality, it is an important target for research and treatment because of its high incidence and difficulty in establishing which lesions with precancerous potential will progress to malignancy . The main etiological factor for SCC is the accumulation of UV damage.…”
