tuberculous cervical lymphadenitis masquerding as metastatis from papillary thyroid carcinoma

clinically apparent cervical lymphadenopathy has been found at the initial presentation in 23 to 56 % of cases of papillary thyroid carcinoma. here we report tuberculous lymphadenitis mimicking metastatic lymph nodes from papillary thyroid carcinoma and suggest that tuberculosis apart from metastasis in papillary thyroid carcinoma should also be considered in the etiology of enlarged lymph nodes in such patients, especially in those with risk factors for tuberculosis. therefore, the importance of careful pre-operative evaluation of cervical lymph node metastasis cannot be overestimated, so that patients do not undergo unnecessary neck dissection for other benign conditions.
