Thyroid carcinoma usually appears as a nodule in the anterior aspect of the lower neck. Less Frequently, the primary tumor in the thyroid gland is occult and the lymph node metastases present as the sole manifestation of the disease The nodal metastases usually appear in the lateral neck as a solid nodule and rarely in form of a cystic mass Although cystic nodal metastases have been known to pathologists for many years. In this study, we describe a case of cervical cystic lymph node metastases from occult thyroid papillary carcinoma that clinically mimicked as a branchial cleft cyst. We would like to describe the initial clinical evaluation, radiological investigation, immunohistochemical staining such as p63 and role fine needle aspiration of the cystic contain that can determine the nature of the lesion and give a definitive surgical treatment as total thyroidectomy and followed by radioactive iodine ablation and thyroid hormone suppression.
