[Facial erythrosis]

At the borders of two sister disciplines, facial erythrosis is a fairly disabling microvascular phenomenon, since it appears most frequently in women. From several rather special cases, the authors review the aetiology and differential diagnosis of these manifestations. An attempt is made to explain the pathogenesis of these phenomena. The authors stress the absence of treatment, but base their hopes on certain dimers or tetramers of hyaluronic acid, provided for their use by Dr CURRI.
