びまん性頭部光線角化症に対する5-フルオロウラシル治療効果の評価におけるVISIAカメラの活用

The VISIA camera is a device that captures images of the skin, offering a detailed look at skin health by detecting changes that are often missed during physical exams and by the naked eye. It can help identify changes in UV damage, pigmentation, texture, fine lines, and redness. In dermatology, it has become a useful tool to build targeted treatment plans and follow patient progress over time. We present a case of a male patient diagnosed with diffuse scalp actinic keratoses who was treated with topical 5-fluorouracil (5-FU). VISIA images were taken before treatment, at one week, and again three months following therapy. The images were reviewed for changes in UV spots, texture, and other generalized spots. Results revealed a decrease in UV spots, a temporary improvement in texture followed by a later rise, and no significant change in generalized spots. This case highlights the value of VISIA imaging as an objective method for assessing treatment response and evaluating the effectiveness of 5-FU in the management of actinic keratoses.
