The article presents the clinical and morphological characteristics of different variants of actinic keratosis in 20 patients. It was found that in 18 (90.0%) patients, lesions were localized exclusively to exposed skin areas (face, neck, and back of the hands), while in 2 (10.0%) cases, the rash also appeared on the upper and lower extremities and back. The average patient age was 66.5±3.4 years. Morphologically, 7 cases of hypertrophic, 9 cases of atrophic, and 4 cases of Bowenoid actinic keratosis were diagnosed. The Bowenoid type showed no histological differences from Bowen’s disease. Regardless of the histological variant, the dermis exhibited basophilic collagen degeneration and a dense inflammatory infiltrate, predominantly consisting of lymphocytes.
