We describe the case of a 27-year-old man with Ehlers-Danlos syndrome,
type IV, The patient had recurrent and eventually fatal pulmonary hem
orrhage. Type IV Ehlers-Danlos syndrome is a rare disorder of type III
collagen synthesis. It is characterized by an unusual facies, thin, t
ranslucent skin with venous vascular pattern, and hypermobility of the
small joints. The cause of death is usually due to rupture of a viscu
s or a major arterial hemorrhage and, in women, rupture of the gravid
uterus, Fatal lung hemorrhage in Ehlers-Danlos syndrome, to our knowle
dge, has not been previously described.
