Infrequently, lymphoma starts in the anterior mediastinum. There are 2 categories of lymphoma: Hodgkin’s disease and non-Hodgkin’s lymphoma. Germ cell: A rare mediastinal mass is a germ cell a tumor. They are very rare. These are most often located in the anterior mediastinum, but they may also involve the middle mediastinum. The treatment of lymphoma is primarily chemotherapy and/or radiation therapy and not surgical removal. However, prompt and accurate pathologic diagnosis by surgical biopsy is the essence of successful therapy. Thymic Cyst: Thymic cysts comprise of 1-3% of anterior mediastinal masses. They usually occur in those aged 20-50. Hodgkin’s Lymphoma: There are approximately 8500 new cases of Hodgkin’s Lymphoma annually in the United States, with a bimodal distribution with a peak seen in young adults mean age in the 20s and in patients over age fifty mean age of 65.

Primary mediastinal lymphoma refers to malignant lymphoma that is exclusively or mostly limited to the mediastinum. The most common cell types to arise in the anterior mediastinum include the nodular sclerosing subtype of Hodgkin’s lymphoma, primary mediastinal large B-cell lymphoma, and lymphoblastic lymphoma. Proceeding through the workup of mediastinal masses, the physician can logically proceed from step to step, based on the sex and age of the patient and the location of the mass. After chest x-ray and CT, order other imaging tests as indicated by the most likely diagnosis. Aspirate clearly cystic lesions for diagnosis and cure. Use serum tumor markers, which can definitively diagnose. Lymphoma also more commonly exerts mass effect on adjacent mediastinal structures and involves pericardium more often than thymoma. 16 Thymoma more typically presents as a rounded, off-midline thymic mass. When advanced, thymoma becomes more lobulated and may cross midline, as is often the case with lymphoma. Mediastinal masses are divided into those that occur in the anterior, middle, and posterior mediastinum. The anterior mediastinum extends from the sternum to the pericardium in the inferior region and from the sternum to the brachiocephalic vessels in the superior region.
