Skin disorders in type II Ehlers-Danlos Syndrome (EDS) are characterized by signs of cutaneous hyperdistensibility, skin and vascular fragility, atrophic scars, and articular hypermobility. These features may have less important clinical presentation in the intermediate forms of type II EDS. The authors studied the ultrastructural and quantitative aspects of elastic and collagen fibers in the skin of individuals with subclinical signs of type II of Ehlers-Danlos Syndrome.

Lectin histochemistry combined with glycosidase digestion was used to investigate the presence of glucidic residues and identify the terminal residues and their acceptor sugars in these glands. Quantitative evaluation of lectin-positive sites was made by histophotometrical scanning. Lectin histochemistry demonstrated that the anteromedial portion contains disaccharides sialic acid-D-Gal, sialic acid-D-GalNAc and Fuc-D-Gal, and that the anterolateral portion contains the terminal dimer sialic acid-D-Gal only.
