Abstract：
Several tumors arise from different structures within the mediastinum. Although each type of mediastinal tumor has a predilection for a specific compartment, the progression of growth from one compartment to another can occur. The anterior mediastinum is the site of several tumors that pose interesting diagnostic and therapeutic challenges to thoracic surgeons. The anterior mediastinum is the seat of the majority of neoplastic growths within the mediastinum. Thymomas and lymphomas are the most common pathologies of the anterior mediastinum. Tumors of mesenchymal origin (hemangioma, lymphangioma, lipomas) and their malignant counterparts may occur in any of the mediastinal compartments. Less common tumors of the anterior mediastinal compartment are ectopic thyroid and parathyroid tumors, germ cell tumors, mesenchymal origin tumors, hemangiomas, and cervicomediastinal hygromas. Most of the mediastinal growths usually remain clinically silent until they become large and cause compressive symptoms. Here, we present a case series of five anterior mediastinal tumors consisting of solitary benign teratoma, fibrous benign tumor, malignant fibrosarcoma, hamartomatous chondroma, and malignant thymoma.
摘要：
几种肿瘤产生于纵隔内的不同结构。尽管每种类型的纵隔肿瘤都有特定的区室，可以发生从一个隔室到另一个隔室的生长进程。前纵隔是几种肿瘤的部位，对胸外科医师提出了有趣的诊断和治疗挑战。前纵隔是纵隔内大多数肿瘤生长的所在地。胸腺瘤和淋巴瘤是前纵隔最常见的病理。间质起源的肿瘤（血管瘤，淋巴管瘤,脂肪瘤）及其恶性对应物可能发生在任何纵隔区。前纵隔区不太常见的肿瘤是异位甲状腺和甲状旁腺肿瘤，生殖细胞肿瘤,间充质起源肿瘤，血管瘤,和宫颈纵隔积液。大多数纵隔生长通常在临床上保持沉默，直到它们变大并引起压迫症状。这里,我们介绍了一系列五个前纵隔肿瘤，包括孤立性良性畸胎瘤，纤维良性肿瘤，恶性纤维肉瘤,错构瘤软骨瘤,还有恶性胸腺瘤.
