Chondroblastoma es

El condroblastoma es un tumor benigno poco común derivado de condroblastos. Se encuentra en las epífisis de huesos largos, usualmente en las extremidades inferiores. La localización más común es el fémur distal, seguido por el fémur proximal, humero proximal y tibia proximal.
Este tumor ocurre con mayor frecuencia en hombres que en mujeres, con una edad media de presentación alrededor de los 20 años.
Clínicamente se puede presentar como un niño, adolescente o joven adulto con dolor e hinchazón en articulaciones como el hombro, la rodilla o la cadera. En ocasiones el tumor puede encontrarse en la región espinal ocasionando dolor de espalda. En radiografías, el tumor se presenta como una lesión expansible con calcificaciones en la epífisis.
El curetaje es el tratamiento utilizado para la mayoría de estos tumores.

Chondrosarcoma - Foot and Ankle

Chondrosarcoma is the most common malignant bone tumor in the foot in some reported series. Most chondrosarcomas are low grade, but dedifferentiated chondrosarcoma can occur in the setting of a longstanding benign cartilage lesion such as enchondroma.
The peak age of presentation is in the 50's and 60's, and the to female ratio of 1.5 to 1. It is most common in the femur, humerus, ribs and on the surface of the pelvis. Patients with Ollier's disease (multiple enchondromatosis) or Maffucci's syndrome (multiple enchondromas and hemangiomas) are at much higher risk of chondrosarcoma than the normal population and often present in the third and fourth decade. Symptoms and Presentation:
The lesion presents as a slow growing mass with mild pain.The radiographs will show a lytic lesion which may demonstrate ring and arc formations.
Treatment for low grade chondrosarcoma may include curettage or marginal excision.
