A 94-year-old woman came to the clinic because of itching and pain on the scalp and back. However, the lesion did not look like typical dermatitis but more like actinic keratosis - a precancerous lesion characterized by skin keratinization because of ultraviolet exposure, which may develop into squamous cell carcinoma. Primary physicians should be alert to this skin disease. Skin squamous cell carcinoma usually presents in the basal layer of the epidermis as early as adolescence. Thus, excessive sun exposure should be avoided starting from a younger age. Primary care physicians practicing in rural and fishing villages are likely to discover these skin lesions earlier and provide treatment or refer them to special clinics for further therapy. Primary care physicians can educate these villagers on how to prevent the disease from becoming skin cancer and teach them how to regularly follow up on the progress of skin lesions related to actinic keratosis.
