ReviewCapillary malformation--arteriovenous malformation syndrome: review of the literature, proposed diagnostic criteria, and recommendations for management.
Capillary malformation-arteriovenous malformation syndrome is an autosomal dominant disorder caused by mutations in the RASA1 gene and characterized by multiple small, round to oval capillary malformations with or without arteriovenous malformations. Ateriovenous malformations occur in up to one-third of patients and may involve the brain and spine. Although making the diagnosis is straightforward in some patients, there are other patients for whom diagnostic criteria may be helpful in their evaluation. Here we review the literature regarding capillary malformation-arteriovenous malformation syndrome, propose diagnostic criteria, and discuss the care of patients with this condition.

Case ReportsDermoscopic and histological correlation of an atypical case of pyogenic granuloma.
Pyogenic granuloma (PG) is a common, rapidly growing, benign vascular proliferation of skin and mucous membranes generally showing, on dermoscopy, a typical pattern characterized by a red to dark pink homogeneous area surrounded by a white collarette. A case of PG in a 5-year-old girl showing an atypical dermoscopic pattern characterized by the presence of a central, irregular, whitish-yellow amorphous structure with a peripheral crown of polymorphous, atypical vessels is reported and discussed.
