Abstract:
Ten cases of periosteal (juxtacortical) chondroma were observed in a series of 234 benign cartilaginous tumors of the hand recorded in the Bone Tumor Register of the Orthopaedic Department of the Semmelweis Medical School, Budapest. The X-rays and histology of this slowly growing, juxtacortical, locally active tumor may simulate a chondrosarcoma and may often lead to difficulties in the differential diagnosis. The adequate assessment of the X-ray and histological finding prevents overdiagnosis and unjustified radical surgical therapy.
