Comparing the efficacy and the safety of KOH 5% solution with 5-Fluorouracil cream on patients suffering Actinic Keratosis: A Randomized controlled trial

Figure legend: A 71year-old man with a different actinic keratosis was treated with KOH 5% (red arrays) and 5-FU 5% (blue arrays). As seen in dermoscopic image at baseline (left), follicular yellow and white scale and pseudo-network pattern could be seen in the KOH section (upper part) and follicular yellow and white scale in 5-FU section (lower part). After seven days (middle clinical image), thick necrosis and erosion are evident on the KOH treated part. On the other side, prominent crusting and erosion are seen in the 5-FU treated lesions. Three months after the treatment (right image), a prominent improvement is seen in the lesion treated with both treatments. In the dermoscopic image 3 months after treatment (right), a prominent improvement is seen in yellow and white scale in both images, while linear-wavy vessels did not change in the lower part, and gray dots are more evident in the upper part.
