Abstract

Mediastinal germ cell tumors (MGCTs) are rare neoplasms that typically occur in young men, with nonseminomatous subtypes predominating in this population. The occurrence of such tumors in women is exceedingly uncommon, accounting for a very small fraction of all extragonadal germ cell tumors (GCTs). We present a rare case of a 44-year-old woman diagnosed with a primary mediastinal germ cell tumor (PMGCT) complicated by superior vena cava (SVC) syndrome. The patient initially presented with severe respiratory distress, chest pain, and signs of venous congestion. Imaging revealed a large anterior mediastinal mass compressing the SVC. She was started on systemic chemotherapy with cisplatin and bleomycin, with partial symptomatic relief. Her hospital course was further complicated by anemia, volume overload, and pulmonary infiltrates. This case underscores the importance of considering MGCTs in the differential diagnosis of anterior mediastinal masses in women and highlights the potential for life-threatening complications such as SVC syndrome. Prompt recognition and multidisciplinary management are essential to improving outcomes in these rare but aggressive tumors.
