We report a case of a 50-year-old woman presenting with a solid nodule in each lung. She was previously suspected of having lung cancer and distant pulmonary metastasis on the basis of imaging findings. Surgical pathology revealed that the left lung nodule was adenocarcinoma, but the contralateral nodule was papillary thyroid carcinoma (PTC). We subsequently performed total thyroidectomy, and the histological findings of the resected specimen showed no suspicious tumor tissue. Overall, the results led to a diagnosis of ectopic intrapulmonary PTC with synchronous lung adenocarcinoma. Ectopic intrapulmonary PTC is a rare but true phenomenon that may be easily mistaken for pulmonary metastasis in daily practice. It is important to improve the recognition of ectopic intrapulmonary thyroid tumors to avoid misdiagnosis.
我们报告了一例 50 岁女性，其每侧肺部均有一个实性结节。根据影像学发现，此前怀疑她患有肺癌和肺部远处转移。手术病理学显示左侧肺结节为腺癌，但对侧结节为甲状腺乳头状癌（PTC）。随后我们进行了甲状腺全切除术，切除标本的组织学检查结果显示无可疑肿瘤组织。总的来说，这些结果导致了异位性肺内 PTC 伴肺腺癌同步的诊断。异位性肺内 PTC 是一种罕见但真实的现象，在日常实践中可能很容易被误诊为肺转移。提高对异位性肺内甲状腺肿瘤的认识，避免误诊很重要。
