Cutaneous collagenous vasculopathy (CCV) is a rare acquired idiopathic microangiopathy that affects the superficial cutaneous vessels. We describe the use of intense pulsed light (IPL) treatment in a case of CCV resulting in clinical and dermoscopic improvement. A 73-year-old Caucasian female presented with a rash on the arms and legs spreading proximally. Histopathology revealed abundant superficial dilated telangiectasia with concentric perivascular hyalinized collagen deposition and hyalinized material stained positively for Periodic-acid Schiff-Diastase resistant, confirming a diagnosis of CCV. Intense Pulsed Light (IPL) and Nd:YAG (neodymium-doped yttrium aluminum garnet) test spots were performed, with marked improvement with IPL therapy on follow-up. Two subsequent full IPL treatments were performed on patient’s bilateral arms, exhibiting significant clinical and dermoscopic improvement. Though effective treatments for IPL are scarce in the literature, there are reports of treatment with Multiplex PDL 595-nm/Nd:YAG 1,064-nm laser and optimized pulsed light. Furthermore, comparable entities to CCV such as generalized essential telangiectasia and poikiloderma have also been shown to be successfully treated with IPL. We present the use of IPL for successful cosmetic therapy in a patient with CCV.
