Teratoma quístico maduro en el mediastino. Reporte de caso

Abstract

Background: Mediastinal masses account for 3% of all tumors of the thorax and are common in people aged 30 to 40 years. Mature teratomas represent 10% to 15% of mediastinal masses, are benign lesions, and consist of tissue from all three germ layers. Case description: A 54-year-old male patient with a history of diabetes mellitus type II and gouty arthritis came to the emergency room with precordial pain and sudden dyspnea after physical activity. The chest X-ray showed a mass in the left parasternal area, so other complementary studies were performed, such as computed tomography and magnetic resonance imaging. This pathology was surgically resolved by left anterolateral thoracotomy. The mass was analyzed histopathologically, and a mature cystic teratoma was diagnosed. Conclusion: Mature cystic teratomas are tumors developed from germ cells that can affect the anterior mediastinum and are benign; the medical team will decide the appropriate approach to the tumor from diagnosis to follow-up; the importance of knowing this disease in primary health care is that the physician can refer the patient for treatment in a timely manner.
