Abstract
STUDY DESIGN/MATERIALS AND METHODS
A total of 81 KS nodules (0.5-3 cm size) located in the feet or lower limbs of nine patients (mean age: 78.8 years; age range: 64-86 years) were selected for treatment with Nd:YAG laser (5-7 mm spot, 140-200 J/cm2 fluence, 5 ms triple pulse with 10 ms delay). The laser beam was delivered at the periphery of each nodule using a tilted angle of 30° to 60° according to lesion size in order to better target the feeding vessels located in the inner and basal depth of the lesion and minimize tissue damage. The treatment outcome was evaluated by clinical photograph, videodermatoscopy, and ultrasound scanning performed before and after treatment, and at each monthly follow-up visit.
