Abstract

The most common benign vascular tumor, pyogenic granuloma (PG), does not resolve spontaneously. While the treatment parameters used for pulsed dye lasers (PDLs) are well-known, no objective therapeutic endpoint associated with PDL therapy in PG has been established. In the current study, three cases of PG were treated with a PDL using a 7-mm spot size, 2-6 ms pulse duration, and radiant exposure of 7-9 J/cm 2 with level 1 air cooling. Dermoscopic examination immediately after PDL treatment revealed that the therapeutic endpoints of PDL were a newly appearing dusky violaceous area, an expanding whitish homogeneous area, and a focal crusted rupture. The successful treatment of the lesions indicates the potential application of dermoscopy to determine therapeutic endpoints when treating PG with PDL.
