Treatment of Cutaneous Collagenous Vasculopathy With Pulsed Dye Laser

ObjectivesCutaneous collagenous vasculopathy (CCV) is a rare, idiopathic microangiopathy marked by widespread telangiectasias and histologic vessel wall thickening. Due to its rarity and clinical overlap with other vascular conditions, CCV poses diagnostic and therapeutic challenges. This report highlights the successful use of pulsed dye laser (PDL) therapy in treating a case of extensive CCV.MethodsA 40-year-old woman with a decade-long history of progressive telangiectasias involving the extremities, trunk, and forearms underwent treatment with a 595-nm PDL. Six treatment sessions were conducted over 14 months.ResultsThe patient experienced significant improvement in erythema, telangiectasias, and associated discomfort, with sustained clinical response and substantial cosmetic benefit observed across all treated areas.ConclusionPDL is a safe and effective treatment for CCV, offering both symptomatic relief and cosmetic improvement. This case adds to limited existing literature supporting its use and highlights the importance of individualized laser parameters for optimal outcomes.
