[Tamponade due to a ruptured mature teratoma : A rare case report].

Introduction: Mature teratomas, a diverse group of germ cell tumors, rarely present with complications such as rupture.

Case Presentation: We present a case of a 27-year-old male who was admitted to our hospital with acute dyspnea. A tamponade was diagnosed and the patient underwent a pericardial puncture. Further radiological investigations revealed a large mediastinal teratoma with evidence of rupture, leading to pericardial effusion. Surgical intervention was performed, which involved pericardial drainage and complete resection of the teratoma. Histopathological examination confirmed the diagnosis of a mature teratoma. The patient made a full recovery postoperatively.

Discussion: This rare case underscores the importance of early recognition and prompt surgical management in patients with ruptured mediastinal teratomas to prevent complications. We discuss the clinical presentation, diagnostic workup, and surgical approach to aid in the understanding and management of similar cases.

Conclusion: Mature teratomas are relatively rare benign tumors that rarely present with complications such as tamponade. Management of tamponade remains the same, and complete surgical removal of the teratoma is essential. In general, the outcome is favorable after surgical treatment.
