Solitary osteochondroma of the sacroiliac joint: A case Report

Abstract Background Osteochondroma is the most frequently encountered benign bone tumor, accounting for approximately 9% of all bone tumors. According to current information, the most frequent localizations are the metaphyseal parts of long tubular bones. Multiple neoplasms are seen in 15% of lesions, while the majority occur as solitary tumors. Case presentation We report the case of a 10-year-old female patient with complaints of swelling and pain behind her waist and right posterior pelvic region. On physical examination, there was pain with palpation of the posterior pelvic region where there was swelling. The biopsy result was reported as osteochondroma. It was decided to proceed with conservative follow-up. However, when the patient's complaints started, local excision was performed and the patient's symptoms regressed. The patient's follow-up is continuing by us. Conclusion Osteochondroma is the most common benign bone tumor. There are a variety of treatment options available, from surgical to conservative. Although the most common location is the metaphyses of long bones, it can be seen in many locations. However, with this case report, we believe that the possibility of its occurrence in the sacroiliac joint should also be considered.
