Spondyloepiphyseal dysplasia (SED) tarda is an inherited skeletal
arthropathy. Because
SED tarda involves the
joints and resemble the clinical findings of chronic
arthropathies, this
disease is frequently misdiagnosed as
juvenile idiopathic arthritis (JIA). We
report here on three
patients (
father and his two
daughters) in one
family with
SED tarda. All
patients had
back pain and
polyarthralgia. Their radiographs revealed typical changes for
SED tarda including platyspondyly and dysplastic
bone changes. This
rare disease has major
clinical importance in that it is
similar with JIA or
rheumatoid arthritis.
