The most common neoplasms of the anterior mediastinum are thymomas, lymphomas, and germ cell tumors. Surgical exploration was the routine approach to the diagnosis and management of these tumors. This is no longer true. The appropriate initial treatment of these neoplasms varies from surgical resection to radiation
Tumors involving the mediastinum may be primary or secondary in nature. Primary neoplasms can originate from any mediastinal organ or tissue but most commonly arise from thymic, neurogenic, lymphatic, germinal, and mesenchymal tissues. All primary mediastinal neoplasms, except those of thymic origin, also occur
10 Mar 2014 Full-text (PDF) | Primary anterior mediastinal neoplasms comprise a diverse group of tumors and account for 50% of all mediastinal masses. Thymomas are most common and can be locally invasive and associated with parathymic syndromes. Thymic carcinomas and thymic carcinoids are rare
According to two large series, thymoma, neurogenic tu- mours and benign cysts, taken together represent 60% of patients with mediastinal masses. Significant differ- ences exist between adults and children concerning the respective frequency of various histological types. Neu- rogenic tumours, germ cell neoplasms and
6 Dec 2012 The mediastinum is demarcated by the pleural cavities laterally, the thoracic inlet superiorly and the diaphragm inferiorly. It is further divided into anterior, middle and posterior compartments by many anatomists [2]. Anterior mediastinal tumours account for 50% of all mediastinal masses, including thymoma,
Tumors of the mediastinum represent a wide diversity of disease states. The location and composition of a mass is critical to narrowing the differential diagnosis. The most common causes of an anterior mediastinal mass include the following: thymoma; teratoma; thyroid disease; and lymphoma. Masses of the middle
