This paper presents a case report of a 45-year-old patient in whom multiple actinic keratoses of the scalp consistent with field cancerization were detected during a total body dermoscopic examination. At the same time, a nodular basal cell carcinoma on the right shoulder was identified. Considering the patient's preferences, treatment with a 1927 nm fractional thulium laser was chosen. The first session was well tolerated by the patient and led to a marked improvement in both clinical and dermoscopic findings. The article further discusses the use of the fractional thulium laser in the treatment of actinic keratoses and its role among other therapeutic approaches.
Keywords: actinic keratosis, field cancerization, fractional thulium (1927 nm) laser, laser therapy.
