A Papillary Thyroid Micro-Carcinoma with Lymph Node Metastasis: Report of a Case

Abstract

We experienced a case of thyroid microcarcinoma with lymph node metastasis. A 68-year-old woman presented with the complaint of common cold-like symptoms. We performed chest CT. The CT showed no pneumonia, but multiple masses were seen in both lobes of the thyroid. The ultrasonography revealed multiple lesions in her thyroid. We performed aspiration biopsy cytology for these thyroid tumors. One tumor, located in the left lobe, 5 mm in diameter, was diagnosed as Class IV. The other tumors were diagnosed as Class II. Subtotal thyroidectomy with lymph nodes dissection (D1) was performed. The pathological diagnosis was papillary carcinoma of the thyroid with paratracheal lymph node metastasis. It is known that the prognosis of microcarcinoma of the thyroid is good. However, microcarcinoma of the thyroid with lymph node metastasis requires careful serial observations.
