Abstract：
Osteochondromas are bone lesions composed of medullary and cartilaginous bone covered by a cap of hyaline cartilage. The presence of medullary and cortical bone with the continuity of the tumor is pathognomonic for osteochondroma and aid in establishing the diagnosis. We report a case of a two-year-old girl who presented to our clinic following her mother noticing a palpable, growing, and painful mass on her left scapula. There was no limitation in the range of motion. A clear-cut mass was seen on the dorsal aspect and palpated measuring around 2.5x3 cm. Surgical excision of the mass followed by histologic examination confirmed osteochondroma. Upon follow-up, the patient had no pain and had a full range of left shoulder motion without discomfort or pain. In conclusion, scapular exostoses are very rare and more so when they present dorsally. Symptomatic lesions can be managed effectively with surgical excision of exostosis.
摘要：
骨软骨瘤是由透明软骨帽覆盖的髓质和软骨骨组成的骨病变。具有肿瘤连续性的髓质和皮质骨的存在是骨软骨瘤的病理标志，并有助于建立诊断。我们报告了一个2岁女孩的案例，她的母亲注意到一个明显的，成长,她的左肩胛骨上有疼痛的肿块。运动范围没有限制。在背侧上看到清晰的肿块，触诊约2.5x3cm。手术切除肿块，然后进行组织学检查，证实骨软骨瘤。在后续行动中，患者没有疼痛，左肩活动范围很广，没有不适或疼痛。总之,肩胛骨外生体非常罕见，当它们背侧出现时更是如此。通过手术切除外生体可以有效地处理症状性病变。
