Description : The Ehlers-Danlos syndromes (EDS) are a group of heritable connective tissue disorders
that share the common features of skin hyperextensibility, articular hypermobility,
and tissue fragility (Beighton, 1993). In the Villefranche classification of EDS (Beighton
et al., 1998), 6 main descriptive types were substituted for earlier types numbered
with Roman numerals: classic type (EDS I and EDS II, 130010), hypermobility type (EDS
III, 130020), vascular type (EDS IV, 130050), kyphoscoliosis type (EDS VI, 225400),
arthrochalasia type (EDS VIIA and VIIB, 130060), and dermatosparaxis type (EDS VIIC,
225410). Six other forms were listed, including a category of 'unspecified forms.'
Major and minor diagnostic criteria were defined for each type and complemented whenever
possible with laboratory findings. The main features of classic Ehlers-Danlos syndrome
(EDS I and EDS II) are loose-jointedness and fragile, bruisable skin that heals with
peculiar 'cigarette-paper' scars (Beighton, 1993). In EDS I, skin involvement is marked
and joint laxity is generalized and gross, with musculoskeletal deformity and diverse
orthopedic complications. Prematurity occurs in approximately 50% of cases. Internal
complications such as aortic and bowel rupture may occasionally occur. EDS II has
all the stigmata of EDS I, but to a minor degree, and some patients may easily remain
undiagnosed (summary by Steinmann et al., 2002).;
