The child's skin microcirculation (MCC) undergoes changes from the first days of life until adolescence. Through video capillaroscopy (VC), in vivo and non-invasive visualization of the CCM is accessed in children of any age. The site of the election is the nail fold of the fingers of the hands. The capillary loops arranged in a crown over the nail matrix and the superficial vascular plexus are observed. The newborns present a primitive network, which later evolves reaching around 10 years the parameters similar to the adult. There are structural differences in MCC if the findings in children are compared with those of adults. In children the capillary density per linear millimeter is lower, the tortuosity index is higher, the superficial vascular plexus is more visible and bizarre capillary forms are found Knowledge of the parameters of MCC preserved in children will be of great importance in the diagnostic exploration of pathologies that affect this vascular territory such as rheumatic diseases.
