Abstract

A 78-year-old man consulted for acute exacerbation of chronic obstructive pulmonary disease (COPD) and an incidental finding of an anterior mediastinal tumor on chest radiograph was noted on admission. Chest computed tomography (CT) revealed a fat-containing mediastinal mass with solid component. Mediastinal liposarcoma was the initial diagnosis based on image characteristics but histopathologic examination of the excised tumor revealed lymphoma infiltration of the mediastinal adipose tissue. To our knowledge, this is the first case report of lymphomatous growth in mediastinal lipomatosis.

摘要

一名78岁男性因慢性阻塞性肺疾病（COPD）急性加重前来就诊，入院时胸部X线片偶然发现前纵隔肿瘤。胸部计算机断层扫描（CT）显示纵隔肿块含脂肪成分及实性成分。根据影像特征，初步诊断为纵隔脂肪肉瘤，但切除肿瘤的组织病理学检查显示纵隔脂肪组织有淋巴瘤浸润。据我们所知，这是纵隔脂肪瘤病中淋巴瘤生长的首例病例报告。
