This review article provides an overview of the etiology, pathogenesis, clinical presentation, diagnosis, and treatment methods for actinic keratosis, keratoacanthoma, and Bowen’s disease. The provoking factors are described, where the main importance is attached to insolation, previous immunosuppression and immunodeficiency and trauma. The pathogenesis of these diseases is described in the form of cascade models. Various clinical forms and their main dermatoscopic features, suitable for digital processing in automated diagnostic systems, are presented. A stepwise approach to the treatment of these nosologies is described, and a preliminary prognosis is assessed based on the duration of progression and the likelihood of transformation into squamous cell carcinoma. Given the fact that dermato-oncologists have not yet come to a consensus on the classification of the described diseases, in this article they are considered as a borderline, thereby demonstrating a fine line of transition from a precancerous state to cancer in situ. |
