Thymolipoma is a rare, slow-growing, benign tumor that arises from the anterior mediastinum and corresponds to 2% to 9% of all thymic neoplasms. We present the case of a 49-year-old man who had a large heterogeneous mass with areas of soft tissue and fat tissue located on the anterior mediastinum and right hemithorax. After resection, histologic analysis confirmed the diagnosis of a giant thymolipoma containing solid components that corresponded to thymomas B1, B2, and B3. We discuss the occurrence of an atypical variant of thymolipoma containing three types of thymomas inside.
胸腺瘤是一种罕见的、生长缓慢的良性肿瘤，起源于前纵隔，占所有胸腺肿瘤的 2%至 9%。我们报告了一例 49 岁男性患者，其前纵隔和右胸腔存在大的混杂性肿块，伴有软组织和脂肪组织区域。切除后，组织学分析证实诊断为含有实性成分的巨大胸脂肪瘤，这些实性成分对应胸腺瘤 B1、B2 和 B3。我们讨论了一种罕见的胸脂肪瘤的发生，其内包含三种类型的胸腺瘤。
