Malignant tumors often are symptomatic and have considerable bulk compared with their benign counterparts. The most common primary malignant tumors of the anterior mediastinum include invasive thymomas, seminomas, nonseminomatous germ cell tumors (GCTs), malignant teratomas, and lymphomas. Commonly, at presentation, these masses manifest clinical symptoms as a result of either extrinsic compression of neighboring mediastinal structures or due to paraneoplastic syndromes. It is important to identify the specific pathology of these tumors, as each of these clinical entities requires a unique treatment strategy with different clinical outcome and prognosis.
