Congenital Cutis Marmorata Telangiectasia (CCMT) is a skin vascular malformation of low flow compromi-sing venous and capillary vessels. Of unknown origin, it shows in an estimated 1/3 000 births. In over 90% of cases it can be seen since birth, although it can appear on the first few days after. Clinical manisfestation includes poorly defined reticular erythematopurpureal maculae, frequently associated to áreas of segmental, asymetric skin atrophy, most often seen in the lower extremitie. The diagnosis is mostly clinical, important to make as it is associated in 30%) of cases to other congenital abnormalities. No specific treatment is required, with spontaneous resolution. Prognosis is good, depending on the associated malformations. Four patients are described in this paper, as a reminder of the clinical entity.
