Dysplasia epiphysealis hemimelica of the proximal tibia showing epiphyseal osteochondroma in an adult.
A 33-year-old woman was referred to our hospital complaining of pain and a tumorous lesion in her left knee joint in the absence of any history of trauma. Radiological examinations demonstrated an osseous mass originating from the epiphysis of the proximal tibia, with a continuous osteoblastic lesion involving the lateral half of the epiphysis. The pathological diagnosis of these lesions was compatible with that of osteochondroma. The clinical and pathological features of this case were considered to be identical with those of dysplasia epiphysealis hemimelica, although this patient was older than patients described in previous reports, and demonstrated no other symptoms such as valgus or varus deformity or limb-length discrepancy.
