Laser Therapy of Cutis Marmorata Telangiectatica Congenita Vascular Malformation

The purpose of this study is to determine a long-term effectiveness of a 532 nm and 1064 nm large spot laser with contact cooling in the treatment of CMTC. Cutis marmorata telangiectatica congenita (CMTC) is a rare, congenital, vascular disorder characterized by dilated capillaries and veins, in all layers of the dermis and subcutaneous tissue. It manifests itself as erythematous-to-violaceous, reticulated, net-like, or marbled-appearing patches on the skin. Two types of CMTC have been observed: isolated and classic. The aetiology of CMTC is not well understood. CMTC is most commonly found on the lower limbs, as in the case of the patient in this study. A 45-year-old woman visited Klinika Ambroziak due to vascular malformations on her right thigh, shank, and foot, which included numerous deep lying and serpiginous capillaries with a marbled pattern and visible telangiectasia. Discrete ivory white scarring was visible along dilated vessels and was evident in dermoscopic evaluation. A classic type of cutis marmorata telangiectatica congenita was diagnosed. It was treated with a large spot 532 nm and 1064 nm millisecond laser with contact cooling, as well as a picosecond 1064 nm laser with the diffraction lens. The latter was added to treat associated discrete scarring. Although an immediate response after vascular laser was achieved both clinically and dermoscopically, videodermoscopy performed after five months showed that large capillary loops persisted and clinical improvement was not satisfactory. After the initial treatment, the effectiveness of the laser therapy was noticeable. However, over time the results were disappointing. Effective treatment can be difficult due to regeneration of abnormal vessels and natural tendency to scarring.
