Extraskeletal mesenchymal chondrosarcomas (EMCs) are relatively uncommon, and a location in the upper extremity, especially in the shoulder or axillary region, is rare. Furthermore, the radiographic findings of EMCs do not show any features that distinguish them from other neoplasms, and therefore, definitive diagnoses are made based on histological features. EMC is an aggressive tumor with a poor prognosis, and requires wide surgical excision. However, its treatment may involve peculiarities such as a difficulty in obtaining a proper surgical margin in the axillary region or shoulder. In this report, the authors present two rare cases of EMCs in the axillary region.
骨外间叶性软骨肉瘤(EMCs)相对少见,而发生在上肢,尤其是肩部或腋窝区域的情况更为罕见。此外,EMCs的影像学表现没有任何可将其与其他肿瘤区分开来的特征,因此,确诊需基于组织学特征。EMC是一种侵袭性肿瘤,预后较差,需要广泛手术切除。然而,其治疗可能存在一些特殊情况,比如在腋窝区域或肩部难以获得合适的手术切缘。在本报告中,作者介绍了两例罕见的腋窝区域EMCs病例。
