Primary thyroid squamous cell carcinoma is extremely rare. We report a case of primary thyroid squamous cell carcinoma diagnosed using F-FDG PET/CT. The patient presented with left axillary lymphadenopathy as the initial symptom. Fine-needle aspiration of the axillary lymph nodes indicated metastatic squamous cell carcinoma. To identify the primary tumor, the patient underwent an F-FDG PET/CT scan, which revealed a mass in the thyroid and multiple enlarged lymph nodes with abnormal FDG uptake. Pathological examination of the axillary lymph nodes and thyroid biopsy confirmed the diagnosis of primary thyroid squamous cell carcinoma with lymph node metastasis.
原发性甲状腺鳞状细胞癌极为罕见。我们报告一例通过F-FDG PET/CT诊断的原发性甲状腺鳞状细胞癌病例。患者以左腋窝淋巴结肿大为首发症状。腋窝淋巴结细针穿刺显示为转移性鳞状细胞癌。为确定原发肿瘤,患者接受了F-FDG PET/CT扫描,结果显示甲状腺有一肿块以及多个FDG摄取异常的肿大淋巴结。腋窝淋巴结的病理检查及甲状腺活检确诊为原发性甲状腺鳞状细胞癌伴淋巴结转移。
