A Case of Cystic Lymph Node Metastasis from Thyroid Papillary Microcarcinoma / 대한갑상선학회지

ABSTRACT

Papillary carcinoma is the most common type of thyroid cancer, usually presenting as a thyroid mass. Presentation in cervical nodes alone, with no clinical suspicion of thyroid tumor, also occurs. Lymph node metastasis from papillary carcinoma of the thyroid may undergo cystic transformation. This occurrence is seldom encountered in clinical practice and in cases of microcarcinomas the diagnosis may be difficult, resulting in a delay of the correct diagnosis and of therapy for the primary tumor. We present a rare case of solitary cystic lymph node metastasis of papillary microcarcinoma of the thyroid.
