Abstract

Thyroid nodule is the most common presentation of thyroid carcinoma. Considering the indolent course of the disease, indeed, the papillary thyroid cancer (PTC) microcarcinoma puts much debate regarding large-scale cohorts on patient follow-up over several decades to detect differences in aggressiveness and outcome [1]. Lymph node metastases might be the salient manifestation of the disease. The nodal metastases usually appear in the central and to a lesser degree in the lateral neck mostly as a solid nodule and rarely in form of a cystic mass. In this study, we describe a case of lymph node metastasis from thyroid papillary carcinoma that clinically and radiologically mimicked a carotid body tumor and despite all pre-surgical evaluations; papillary thyroid carcinoma was detected in the final histopathology report. We intend to describe the initial clinical evaluation, radiological survey and pathology report.
