Thymic epithelial tumours (TETs) are rare lesions that represent less than 1% of all malignancies in adults. Presentation occurs in three ways: asymptomatic, with local thoracic symptoms or with paraneoplastic symptoms. Heterotopic ossifications are rare histological features in neoplasms and non-neoplastic lesions. Here, we present a 49-year-old male patient with a thymoma type B2 mimicking an aortic aneurysm. Alongside the thymoma, a cholesterol granuloma with unusual ossification features was found as well. This clinical presentation and pathological diagnosis are unusual findings.
胸腺上皮肿瘤（TETs）是罕见病变，在成人所有恶性肿瘤中占比不到1%。其临床表现有三种方式：无症状、有局部胸部症状或有副肿瘤症状。异位骨化是肿瘤和非肿瘤性病变中罕见的组织学特征。在此，我们报告一名49岁男性患者，其B2型胸腺瘤酷似主动脉瘤。除胸腺瘤外，还发现了一个具有异常骨化特征的胆固醇肉芽肿。这种临床表现和病理诊断均为不寻常的发现。
