Actinic keratosis (AK) usually presents as palpable discrete and non-discrete patches of erythema and scale on sunexposed body sites of fair-skinned individuals. AK can be classifi ed clinically into hyperkeratotic, non-hyperkeratotic and pigmented variants with the former 2 variants much more commonly seen. Current treatment recommendations are primarily determined by lesion load, lesion morphology and corresponding affected body site location, with limited focus on AK variants . We investigate the ratio of hyper- keratotic vs non-hyperkeratotic AK variants in chronic sun-exposed body sites including face, dorsal hands and forearms as well as legs of 40 participants using clinical examination and digital photography, including a cohort of organ transplant recipients on immunosuppressive therapy. Knowledge of the ratio of hyperkeratotic and non-hyperkeratotic actinic keratoses may be useful for the elaboration of evidence-based management recommendations.
