Thymomas are composed of a mixture of epithelial and lymphoid cells. When the lymphoid cells predominate, the possibility of malignant lymphoma must be considered. Recently, a thymoma mimicking lymphoblastic lymphoma was reported in this journal as a diagnostic pitfall in a mediastinal aspiration. We encountered another diagnostic pitfall at the other end of the spectrum: a thymoma with a dominant epithelial component in which a papillary carcinoma of thyroid had to be considered in the differential diagnosis.
胸腺瘤由上皮细胞和淋巴细胞混合组成。当淋巴细胞占主导时，必须考虑恶性淋巴瘤的可能性。最近，本刊报道了一例类似淋巴母细胞淋巴瘤的胸腺瘤，这是纵隔穿刺活检中的一个诊断陷阱。我们在另一个极端遇到了另一个诊断陷阱：一种以上皮成分占主导的胸腺瘤，在鉴别诊断中必须考虑甲状腺乳头状癌。
