abstract
- Primary metaphyseodiaphyseal chondroblastoma is rare. To our knowledge, very few such cases have been reported in the English literature. Insidious onset of pain is the most common complaint in patients with chondroblastoma. A clinical presentation of constitutional symptoms along with a metaphyseodiaphyseal lesion on radiographs in a young child usually points toward a diagnosis of Ewing's sarcoma or infection. Here, we document a case of metaphyseodiaphyseal chondroblastoma of femur in a 6-year-old child presenting with chief local complaints of an intermediate onset pain and swelling along with systemic complaints of fever and malaise. The patient was operated by excision of the tumor and reconstruction using autogenous-free fibular graft.
