Summary Background and objectives Because of the heterogeneity in port‐wine stains, a number of them prove resistant to treatment with the pulsed‐dye laser (PDL). A new variable pulse‐duration PDL improves a refractory port‐wine stain. Study design/materials and methods A 26‐year‐old man with a congenital port‐wine stain underwent eight treatments with the 1.5‐ms pulse‐duration PDL resulting in minimal improvement. A single treatment was then administered with the 3‐ms pulse‐duration PDL. Results Initial results of treatment with the 3‐ms pulse‐duration PDL on this patient's port‐wine stain show dramatic clearance in areas previously treated with significantly higher fluences, an identical spot size, but with a pulse duration half as long. Conclusion Vessel heterogeneity may require changing pulse durations once a port‐wine stain or a portion of a port‐wine stain becomes refractory to given pulse‐duration.
