PUVA keratosis is a pre-cancerous keratotic skin lesion that arises from exposure to psoralen and ultraviolet A light therapy.[1] It presents as a small scaly bump in the skin with a wide base and warty look.[1]
It may appear similar to actinic keratosis, but differentiated by its appearance under the microscope; PUVA keratosis does not have solar elastosis.[2]
