A Case of Spondyloepiphyseal Dysplasia Tarda Coexisting With Osteoporosis and Mimicking Spondyloarthropathy

Spondyloepiphyseal dysplasia tarda (SEDT), which is characterized by short stature with short trunk, may cause barrel chest, kyphoscoliosis, platyspondyly, coxa vara and genu varum/valgum deformities due to delayed formation of epiphyses. The association of SEDT with osteopenia and osteoporosis has been reported. Chronic back and buttock pain, swelling of the joints and morning stiffness are some of the clinical findings of SEDT which can be confused with inflamatory diseases. In this article, we present a 19-year-old male patient with SEDT who was diagnosed as having spondyloarthropathy because of back and buttock pain and morning stiffness associated with osteoporosis.
