[Chondrosarcoma of the upper end of the femur; radiotherapy, resection of the epiphysis, acrylic prosthesis; remote results (6 years)].

Chondrosarcoma is a malignant tumor that produces cartilage matrix. Occurs in the fourth to sixth decades and has a male to female ratio of 2/1. It is most common in the long bones and on the surface of the pelvis. The authors present a case of chondrosarcoma of the upper end of the femur of a 50-year-old female patient who has come in our Department of Orthopedics and Traumatology two month ago, complaining of severe and persistent pain in the left hip joint and presenting limitation of adduction movement, limitation of internal-external rotation movements, and also could not be able to do thigh flexion on the abdomen. The woman presented a four-month history of persistent and severe pain, not assigned at anti-inflammatory drugs. Laboratory tests not had shown any significance. On radiographies and magnetic nuclear resonance the lesion was shown very clear, deciding for biopsy. The tumor had been large surgical excised with safe limits. Histopathology indicated the histological feature as a differentiated chondrosarcoma, grade III. Our patient has started the chemotherapy and radiation.
