To describe Cutis Verticis gyrate (CVG) in cases found in an institutionalized people facility in Colombia. Case series with 65 male adult in-patients, describing socio-demographic and clinical variables. Prevalence of 5.9 % was higher than expected in the general population (1:100.000 in males). Mean age: 38.5 years, most illiterate (98.46%). The most frequent diagnosis was profound mental retardation in 59 (90.77 %) cases, with high multi-axis comorbidity. Folds range from 1 to 16. Age of onset and type of CVG couldn't be established.
 This is the largest case series reported from a single institution. There is need of further study to determine type, origin, and evolution of the sign.
