Fig 1 (A) Transthoracic echocardiogram (apical four-chamber view) demonstrating an extracardiac mass (star) almost completely compressing the left atrial cavity. LV = left ventricle. (B) Computed tomographic scan of the thorax revealing a large, 8.5 × 6.8 × 6.8 cm sized, round lesion (star) in the middle and posterior mediastinum at the level of the left atrium. Compression of the left atrium is obvious. LV = left ventricle. (C) Right extended anterolateral thoracotomy revealed the large, round, solid, posterior mediastinal mass (star). (LA = left atrium; V = vertebrae.) The Annals of Thoracic Surgery , DOI: ( /j.athoracsur ) Copyright © 2015 The Society of Thoracic Surgeons Terms and Conditions

Fig 2 (A) Macroscopic view of the specimen showing a well-demarcated tumor. (B) The cut surface reveals a lobulated dark mass with sites of hemorrhage and necrosis. (C) Microscopic examination (×50) showing the morphologic characteristics consistent with malignant melanoma with melanin production. (D) Diagnosis confirmed by the positivity of several immunohistochemical markers such as Vimentin, HMB-45, S-100 protein (not shown), and Melan A (×200).
