Abstract: Primary bone tumors pose, in our Gabonese context, diagnostic and management problems due to their rarity and the often late circumstances of discovery. In our department, a few studies concern primary bone tumors. This was a retrospective study with description which took place from June 1, 2018 to June 1, 2022. Statistical analysis was performed with Microsoft Excel version 2019. Categorical variables were expressed as percentages and the interpretation was made by comparing the percentages. We collected 30 patients including 17 men and 13 women. The age group of [0-20 years old] was predominant (60%) with an average age of 22.1 years. Pupils and students predominated with 66.7%. Circumstances of discovery were pain in 43.3% and swelling in 26.7%. The tibia was the most concerned bone with 40% followed by the femur with 26.7%. Among benign tumors, giant cell tumors were predominant with 23.3%, while osteosarcomas predominated among malignant tumors with 20%. In surgical treatment, excision was the most used method with 26.6%. We noted 30% of complications. With a follow-up of 12 months, the evolution without signs of recurrence was predominant with 76.7% (n=23).
