This study aimed to determine the frequency and distribution of bone tumours of the scapula as well as the histological and anatomical characteristics of these rare lesions in a large case series.
The records of all lesions of the scapula collected from 1975 to 2018 in our bone tumour registry and institute of pathology were evaluated. During these 43 years, 223 cases were identified. Analysis included assessment of age, gender, side, imaging findings, tumour location, and histological evaluation with the assignment of each lesion to one of the bone tumours according to the World Health Organization (WHO) classification of bone tumours.
Bone tumours of the scapula were found in 193 cases. Mean patient age was 38.4 years (2.6-82.4). Most of the lesions were of cartilage origin (47%). 59 bone tumours were benign (30.6%), 29 were intermediate (15.0%), and 105 were malignant (54.4%). The most commonly found bone tumour was Osteochondroma (23.3%), followed by Chondrosarcoma (17.6%), Bone metastases (16.6%), Ewing sarcoma (8.8%), and Osteosarcoma (7.8%). The percentage of malignant bone tumours increased with increasing age. In patients >50 years of age, 91% had a malignant lesion of the scapula.
Evaluation of 193 bone tumours of the scapula revealed a high incidence of malignancy in this series, while increased patient age was identified as a potential risk factor for the development of a malignant lesion of the scapula. These findings highlight the importance of early diagnosis and treatment of suspicious lesions of the scapula to improve patient outcome.
本研究旨在确定肩胛骨骨肿瘤的发生率和分布情况，以及在一个大型病例系列中这些罕见病变的组织学和解剖学特征。
对1975年至2018年期间从我们的骨肿瘤登记处和病理研究所收集的所有肩胛骨病变记录进行评估。在这43年中，共识别出223例病例。分析内容包括年龄、性别、患侧、影像学表现、肿瘤位置评估，以及根据世界卫生组织（WHO）骨肿瘤分类将每个病变归类为一种骨肿瘤的组织学评估。
在193例病例中发现了肩胛骨骨肿瘤。患者平均年龄为38.4岁（2.6 - 82.4岁）。大多数病变起源于软骨（47%）。59例骨肿瘤为良性（30.6%），29例为中间型（15.0%），105例为恶性（54.4%）。最常见的骨肿瘤是骨软骨瘤（23.3%），其次是软骨肉瘤（17.6%）、骨转移瘤（16.6%）、尤因肉瘤（8.8%）和骨肉瘤（7.8%）。恶性骨肿瘤的百分比随年龄增长而增加。在年龄大于50岁的患者中，91%患有肩胛骨恶性病变。
对193例肩胛骨骨肿瘤的评估显示，该系列中恶性肿瘤的发生率较高，而患者年龄增加被确定为肩胛骨恶性病变发生的潜在危险因素。这些发现凸显了早期诊断和治疗肩胛骨可疑病变以改善患者预后的重要性。
