Mature teratoma is the most common primary germ cell tumor in the mediastinum. On rare occasions, cystic teratomas rupture in adjacent structures, such as pleural space, pericardium, lung or tracheobronchial tree. We present a case of a mediastinal mature cystic teratoma in 16-year-old female with complex rupture into the lung, bronchus and skin. Mature mediastinal teratoma fistulized to the sk...

Although mature teratomas are a common cause of anterior mediastinal tumors, they rarely arise in other mediastinal compartments. We describe a 16-year-old boy with a 20×10 cm mature cystic teratoma in the posterior mediastinum. This case emphasizes the importance of correct diagnosis if a mediastinal mass with the typical features of a mature teratoma-such as fat, cystic compartments, calcific...

Mediastinal mature teratoma is the most common form of germ cell tumors, often located in the anterior mediastinum. A posterior mediastinum location has rarely been described. We report a case of a posterior mediastinal mature teratoma in a 37-year-old patient and a literature review, through which we describe the diagnostic and therapeutic difficulties inherent in this particular location of t...

ABSTRACT Mediastinal masses can be challenging to the surgical team and anesthetic considerations vary according location, pathology, approach, patient comorbidities. We report case of a 21 cm symptomatic intrathoracic teratoma in postpartum with history poliomyelitis. Significant challenges were presented for induction, potential extracorporeal membrane oxygenation, use neuraxial pain techniqu...

Mediastinal teratomas are rarely reported in children. We report a 12-year-old child, diagnosed and treated as empyema thoracis in a peripheral setting for 18 months. In our centre, CT scan performed revealed a well circumscribed multiloculated cystic lesion containing fat, bone and teeth, suggestive of a teratoma. The mass was excised and found to be an infected posterior mediastinal teratoma,...

We report a case of a posterior mediastinal mature cystic teratoma with rupture secondary to blunt chest trauma in a 20-year-old male involved in a motor-vehicle accident. Initial treatment was guided by Advanced Trauma Life Support and a tube thoracostomy was performed for presumed hemothorax. The heterogeneous collection within the thoracic cavity was discovered to be the result of a ruptured...

Immature mediastinal teratoma is very rare, found in only 1% of all mediastinal teratomas. Raised serum alpha feto-protein acts as important surrogate marker for both diagnosis and follow up in such cases. Surgery and adjuvant chemotherapy are keys in the management, especially in patients older than 15 years of age. We present a 14-year-boy presenting clinico-radiologically as left sided massi...

We report a rare case of rhabdomyosarcoma spontaneously arising in an anterior mediastinal teratoma in a 47-year-old male. The patient was found to have an anterior mediastinal mass on a chest X-ray, which was taken two months before his presentation to Asan Medical Center. A subsequent computed tomography scan revealed an 8.9×7.1×8.0 cm heterogeneous mass in the anterior mediastinum. He underw...
