Cutis marmorata telangiectatica congenita: laser doppler fluxmetry evidence for a functional nervous defect.

We report a 5-month-old infant with cutis marmorata telangiectatica congenita (CMTC) without associated abnormalities and unusual hemicorporal vascular markings. Laser Doppler fluxmetry of the involved skin, carried out for the first time, and the measurement of the transcutaneous partial pressure of oxygen indicate a functional disturbance, which may be the expression of an alpha-adrenergic innervation deficit of the cutaneous terminal blood vessels.
