Researchers of a study aimed to identify any dermoscopic changes in skin improvement in those with chronic plaque psoriasis with narrow-band ultraviolet B phototherapy. They also sought to assess the function of dermoscopy in patient monitoring. A total of 30 patients were included in the study, and they were prescribed narrowband ultraviolet B phototherapy for three months in accordance with the condition of their disease. Psoriasis area and severity index calculations found a considerable link between changes in vessel patterns and improvements that were seen in the treatment of psoriatic lesions. Those with globular blood vessels were found to have weak clinical results. Researchers concluded that dermoscopy is a tool that is fast and easy to predict responses of psoriatic patients to phototherapy with the assessment of vascular patterns.
