Mediastinal teratomas are often asymptomatic. When symptoms are present, they relate to mechanical effects and include chest pain, cough, dyspnea, or symptoms related to recurrent pneumonitis. Many patients present with respiratory findings, and the pathognomonic finding of trichoptysis (cough productive of hair or sebaceous material) may result if a communication develops between the mass and the tracheobronchial tree. Other serious presentations are superior vena cava syndrome or lipoid pneumonia. Mediastinal teratomas are occasionally discovered incidentally on chest radiographsa. [39, 6, 16, 21]
