Teratoma: Operative Findings, Preparation (Tumor Anterior Mediastinum)

metu_10a_n.jpg and metu_10b_n.jpg: Operative findings and preparation of an inhomogeneous mass in the anterior mediastinum of a 5.8-year-old girl. In the midline medially of the left lung a large and polymorphic mass is visible which contains at the bottom a grey and homogeneous part and at the top a yellowish and inhomogeneous part. It is recognizable even more distinctly in the preparation; some of the reddish elements are vessels. Notice the length of the mass of 16 to 17 cm. The diagnosis is an adult differentiated teratoma.
