Abstract
A case of a fit 65-year-old male with a long history of recalcitrant Disseminated Superficial Actinic Porokeratosis (DSAP) treated with Volumetric Modulated Arc Radiotherapy (VMAT) is presented. The whole circumference of both lower legs from knees to ankles were simultaneously treated to 43.2 Gray (Gy) in 24 fractions, one fraction short of the prescription dose of 45 Gy in 25 fractions. There was in-field clearance of DSAP at ten weeks.
