Which lymphoma is commonly associated with an anterior-superior mediastinal mass and SVC syndrome?

• A. Burkitt lymphoma
• B. Diffuse large B-cell lymphoma
• C. Hodgkin lymphoma
• D. Lymphoblastic lymphoma

Answer: (D)

An anterior mediastinal mass that leads to SVC syndrome most strongly points to a thymic-origin lymphoid tumor, specifically T-cell lymphoblastic lymphoma. The thymus sits in the anterior superior mediastinum, and T-cell lymphoblastic lymphoma commonly presents in adolescents as a bulky mediastinal mass that can compress the superior vena cava, causing edema of the face and upper body, headaches, and venous congestion typical of SVC syndrome. Other lymphomas can involve the mediastinum, but their usual patterns differ. Burkitt lymphoma tends to present as rapidly growing tumors in the jaw or abdomen; diffuse large B-cell lymphoma is more common in older adults with variable sites; Hodgkin lymphoma can involve mediastinal nodes, especially the nodular sclerosis type in young people, but SVC syndrome is less characteristic than with T-cell lymphoblastic lymphoma.
