A Challenging Case of Heart Displacement by a Large Mediastinal Germ Cell Tumor

Mediastinal germ cell tumors (GCTs) are rare and aggressive cancers originating from the cells in mediastinum. Early detection treatment vital due to their high potential for metastasis recurrence. We present a case of 28-year-old man who exhibited cough shortness breath. Laboratory tests revealed elevated tumor markers, alpha-fetoprotein, beta-human chorionic gonadotropin. Imaging studies displayed large mediastinal mass, causing right displacement mediastinum cardiac tamponade. The biopsy confirmed non-seminomatous GCT, specifically yolk sac tumor. patient experienced pericardial effusion tamponade after receiving two cycles etoposide cisplatin chemotherapy. To relieve tamponade, an emergency pericardiocentesis was performed malignant GCTs necessitate prompt diagnosis utilizing multimodal therapy such as chemotherapy achieve control. Due risk metastasis, vigilant surveillance recurrence is essential, emphasizing need specific criteria accurate early detection.
