Abstract Background Capillary malformation–arteriovenous malformation ( CM ‐ AVM ) is a recently described autosomal dominant disorder that results from mutations in RASA 1 . It has been initially described as multiple CM s affecting several members of the same family, associated with fast‐flow malformations in at least one family member. Objective To report and analyze clinical data on 45 patients with CM ‐ AVM assessed at the Department of Pediatric Dermatology, Ramos Mejía Hospital (Buenos Aires, Argentina). Method Retrospective clinical review of all the patients clinically diagnosed as having CM ‐ AVM over a period of eight years. Results Forty‐five patients were recorded (24 females and 21 males). The age ranged from one month to 44 years. In 36 patients, the stains were congenital; progressive acquired lesions were observed in 39. Family history was positive in 32 subjects. Well defined, round to oval, pink–purple or reddish‐brown macules were found in all the patients; pinpoint red lesions with a pale halo were found in nine cases. The macules were warmer than normal skin in 15 cases and surrounded by a white halo in 26 cases. Three subjects presented associated overgrowth, lymphatic malformation was present in one case, retinal vascular lesion in one patient, and isolated port wine stain in two cases. Three patients also had infantile hemangioma. We had no cases of fast‐flow vascular malformation or combined vascular syndromes. Conclusions CM ‐ AVM is a heterogeneous disorder with phenotypic variability, from fast‐flow malformation, limb enlargement, or Parkes Weber syndrome to multiple CM s without internal involvement.
