Abstract

INTRODUCTION

The purpose of this study was to assess the cases that were examined with a prediagnosis of tumor but were found to have tumor-like lesions as a result of pathological examination.

METHODS

349 cases that had undergone advanced examination with a prediagnosis of bone and soft tissue tumor and had been found not to have tumor between January 1987 and January 2012 were examined retrospectively. The cases were assessed in terms of age, gender, localization, pathological diagnosis and features. The data were analyzed by SPSS 15.0. Shapiro-Wilk test was used to find out whether the data were distributed normally.

RESULTS

175 (50.1%) of 349 cases were men, while 174 (49.9%) were women and the average age was 35.3. 101 (28.9%) of the lesions were localized in the femur and thigh while 56 (16%) were localized in tibia, fibula and calf. Results of the examinations of lesions showed that 79 (22.6%) were normal tissue, 74 (21.2%) were inflammatory and 63 (18.1%) were osteomyelitis. Our data showed that infections and normal tissue reaction were most commonly mistaken for tumor.

DISCUSSION AND CONCLUSION

Each case with the clinic and features which bring to mind bone and soft tissue tumor should be accepted as tumor unless otherwise proven and advanced examination and treatment should be organized accordingly. This approach will allow the early diagnosis and treatment of tumor which causes morbidity and mortality.
