Tumor de células gigantes de fémur distal com metástases pulmonares

gian cell is normally a benign primary skeletal lesion located in the epiphysis of the long bones. it is more frequente in the third and fourth decades of life but can exhibit the behaviour of a malignant tumour with distal metatasis. up to 10% of patients present distal metatasis, usually in the lung, and it is concomitant to recurrence in the primary site. the treatment of primary tumour is extensive surgical resection. we report a case of a 35-year-old patient with lung metatases 21 months after curettage of giant cell tumour in distal femur.
