Precancerous conditions of the skin are changes to the skin cells that make them more likely to develop into cancer. Actinic keratosis is not yet cancer. The most common precancerous skin lesions are actinic keratoses, Bowens disease, and keratoacanthoma. Actinic keratoses appear over the exposed areas of the body as the result of actinic radiation. Bowens disease is most probably secondary to the effects of internal carcinogens Premalignant lesions of the penis include cutaneous horn, balanitis xerotica obliterans, and leukoplakia. The true incidence of progression of each of these to squamous-cell carcinoma is unknown. Bowenoid papulosis, erythroplasia of Queyrat, and Bowens disease are histologically identical to in situ carcinoma Ref Harrison20th edition pg 1345
