Unstimulated Serum Thyroglobulin Levels after Thyroidectomy and Radioiodine Therapy for Intermediate-Risk Thyroid Cancer Are Not Always a Reliable Marker of Lymph Node Recurrence: Case Report and a Lesson for Clinicians

<div>Fine needle aspiration cytology of the left laterocervical lymph-node recurrence detected during the fourth year of follow-up after surgery and radioactive 131I therapy, which showed three-dimensional papillary flaps of medium size cells with pseudoinclusions and grooves which proved compatible with metastasis of papillary thyroid carcinoma (ThinPrep method, Papanicolaou stain, 40X).</div>
