INTRODUCTION
Masses which develop on the surface of the rib bones are rare. The differential diagnosis includes benign and malignant lesions.
CASE PRESENTATION
A 23-year-old European woman presented at an out-patient clinic with a 9-month history of a painless swelling on the right posterolateral side of her chest wall. The case reported here is of a very rarely seen parosteal osteosarcoma of the rib that was treated with wide resection and chest wall reconstruction. There was no evidence of local recurrence or distal metastasis after a 1-year follow-up.
CONCLUSION
Parosteal osteosarcoma is a locally aggressive malignant tumor, and resection with a wide margin is the most appropriate treatment. Correct diagnosis of parosteal osteosarcoma is challenging for an orthopedic surgeon. Although rare, in the differential diagnosis of lesions located on the ribs, parosteal osteosarcoma should be considered and a systematic diagnostic approach should be taken.
引言
肋骨表面出现的肿块较为罕见。鉴别诊断包括良性和恶性病变。
病例介绍
一名23岁的欧洲女性到门诊就诊，其右胸壁后外侧有无痛性肿胀9个月病史。本文报道的病例是一例非常罕见的肋骨骨膜骨肉瘤，采用广泛切除和胸壁重建进行治疗。1年随访后无局部复发或远处转移迹象。
结论
骨膜骨肉瘤是一种具有局部侵袭性的恶性肿瘤，广泛切缘切除是最合适的治疗方法。对于骨科医生来说，正确诊断骨膜骨肉瘤具有挑战性。尽管罕见，但在肋骨病变的鉴别诊断中，应考虑骨膜骨肉瘤，并采取系统的诊断方法。
