摘要
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.

一位94歲女性，因頭皮、背部搔癢、疼痛來醫院就診，但病灶看起來並不是典型的皮膚發炎，日光角化症是由皮膚角質化引起的皮膚癌前病變，可能發展成鱗狀細胞癌，基層醫師應該對這種皮膚病變有所警覺，日光角化症是由太陽光中的紫外線照射，引起的鱗狀細胞癌的早期皮膚病變，也是人類最常見的皮膚癌之一，皮膚鱗狀細胞癌通常早在青春期就出現在表皮的基底層；因此年輕時應避免過度日曬並適當的防曬，尤其是在農村、漁村執業的基層醫師，能夠及早發現這種皮膚發炎，並給予治療或轉診給皮膚專科醫師進一步治療，基層醫師可以衛教這些村民如何預防這種疾病發展成為皮膚癌，並且教導他們如何定期追蹤與日光角化症相關的皮膚病變的癌細胞發展。
