ABSTRACT
The incidence of mediastinal teratomas is low, it's important to recognize them between all the differential diagnoses for mediastinal tumors. The treatment is surgical resection. We report a giant mature cystic teratoma of the mediastinum in a 40-year-old woman. She presented with dyspnea, flu-like symptoms during the previous 5 days. An x-ray complemented with a chest CT scan showed a heterogeneous extrapulmonary multiloculated and predominantly fluid density tumor located at the left side of the mediastinum. The patient underwent resection by video-assisted thoracic surgery (VATS). The tumor was 15 cm in diameter with a predominant cystic component. Histologic examination revealed a mature cystic teratoma. Treatment of these tumors should attempt a complete resection. Open approaches are painful, require a longer recovery and are associated with higher morbidity. VATS has been used to treat these tumors, demonstrating the same effectiveness and advantages over open procedures.
ABSTRACT
We report a case of primary tracheal schwannoma in a 31-year-old woman. She had a previous history of follicular thyroid carcinoma treated surgically and Turner syndrome. In a follow-up computed tomography scan, we found a partially obstructing intraluminal tracheal tumor, which was confirmed by bronchoscopy. The patient was treated by surgical resection and primary tracheal anastomosis. The tumor was 14 mm in diameter, with an intact capsule. Histologic analysis revealed a Schwann cell origin tumor.
