title: Atypical giant chondroblastoma mimicking a chondrosarcoma.
abstract: Chondroblastoma is a rare, benign tumor derived from chondroblasts, commonly presenting in the second decade of life. It is usually found in the epiphysis or apophysis of long bones; however, it may rarely affect flat bones like scapula. Occasionally a histologically typical chondroblastoma may exhibit an aggressive behavior that is not normally associated with benign tumors such as a large size, pulmonary metastases, joint and soft-tissue infiltration and local recurrence. We present a case report of a patient with chondroblastoma showing atypical radiological presentation and non-concordance with age.
