Abstract: Correct histologic diagnosis of musculoskeletal tumors, as soon possible, is quite critic in point of improvement in patients’ prognosis, and possibility and success of the limb sparing interventions. To make an accurate histologic diagnosis, adequate tissue sample is required. Open incisional biopsy has traditionally been used for that reason. However, open biopsies have complication rate of 16 % and these complications affect the treatment plan in 8 % of all patients undergoing biopsy . In recent years, core needle biopsies were started to be used instead of incisional biopsies . Compared to open biopsy, core needle biopsies are less invasive, cause fewer potential complications, and incur less expense. The major concern regarding core needle biopsy is that it provides a limited sample and small tissue cores, in which the histolojic morphology may not be appreciable.
Both, it has reported that, to a large extent, the use of needle biopsies has replaced open biopsy in musculoskeletal oncology practice and it has also reported that it remains controversial whether accurate histological diagnosis can be made only with the material obtained by needle biopsy of musculoskeletal lesions.
The aim of this study is to evaluate the accuracy of the core needle biopsy techniques in musculuskeletal tumors.
