Soft tissue sarcomas (STS) comprise a large group of heterogeneous malignant tumors that form approximately 1% of all adult malignancies. Most sarcomas originate from soft tissue and the rest arise from the bone. Undifferentiated pleomorphic sarcoma (UPS) is an aggressive tumor that usually presents as an asymptomatic subcutaneous mass that exhibits rapid growth with unremarkable skin findings. The diagnosis is usually made with histopathology or immunohistochemistry; once the diagnosis is confirmed, evaluation and workup of the primary tumor, lymph nodes, and metastasis should be made. Treatment is stage-dependent but generally involves en-bloc resection followed by a review of pathology with a discussion of the benefits of adjuvant radiation or chemotherapy. Here, we discuss a case of a 77-year-old patient who presented with a large mass over the right shoulder and echocardiographic findings of cardiac tamponade.
软组织肉瘤（STS）是一组异质性恶性肿瘤，约占所有成人恶性肿瘤的 1%。大多数肉瘤起源于软组织，其余则来自骨骼。未分化多形性肉瘤（UPS）是一种侵袭性肿瘤，通常表现为无症状的皮下肿块，生长迅速，皮肤表现无明显特征。诊断通常通过组织病理学或免疫组织化学进行；一旦确诊，应评估和检查原发性肿瘤、淋巴结和转移灶。治疗取决于分期，但通常包括整块切除，然后对病理进行审查，并讨论辅助放疗或化疗的益处。在这里，我们讨论了一个 77 岁患者的病例，该患者右侧肩部出现一个大肿块，并伴有心脏压塞的超声心动图表现。
