Abstract

Introduction: Actinic keratosis (AK) is precancerous skin lesion that occurs in the sun-exposedskin areas characterized by local intraepidermal dysplasia of different severity (KIN I, KIN II and KIN III). The aim of this research was to study distribution patterns and morphological features of AK histological types. Materials and Methods: The study included skin biopsy material from 68 patients with different clinical forms of AK. The diagnosis of AK was histologically confirmed in 100% of cases. Results: There were 63.21% of men and 36.8% of women among all patients with AK. The average age of patients was 73.3 ± 8.3.The most common clinico-histological forms of actinic keratosis were typical (41.2%), hypertrophic (16.2%), atrophic (14.7%) and pigmentary (11.7%), bowenoid (8.8%), acantholytic (7.4%). Among the rate of epidermal dysplasia there diagnosed cases of KIN І (50%), KIN ІІ (36.8%) and KIN III (13.2%). Conclusions: It was found a direct correlation between KIN I and typical and pigment forms of AK, KIN II and hypertrophic and bowenoid forms of AK.
