Primary squamous cell carcinoma of the thyroid gland (PSCCT) is a rare malignancy that presents with advanced disease and poor prognosis. It is difficult to diagnose PSCCT in its early stage because of its rarity and lack of typical imaging findings. We experienced an elderly woman with PSCCT confirmed by surgery. Although preoperative fine-needle aspiration revealed no malignancy, surgical resection was performed because the ultrasonogram showed diffuse microcalcifications, which suggested malignancy, and clinically, the mass grew rapidly to compress the trachea. Local tumor recurrence was noted at 3 months after surgery. Surgical resection or repeat biopsy should be considered if a cytologically benign thyroid mass shows imaging or clinical features of malignancy.
甲状腺原发性鳞状细胞癌（PSCCT）是一种罕见的恶性肿瘤，常表现为晚期疾病和预后不良。由于其罕见性和缺乏典型的影像学表现，早期诊断PSCCT 较为困难。我们遇到一位老年女性，经手术证实为 PSCCT。尽管术前细针穿刺抽吸未发现恶性肿瘤，但由于超声显示弥漫性微钙化，提示恶性可能，且临床上肿块迅速生长压迫气管，因此进行了手术切除。术后 3 个月发现局部肿瘤复发。如果细胞学良性甲状腺肿块出现影像学或临床恶性特征，应考虑手术切除或重复活检。
