Abstract
Background  Although several factors are thought to predict the occurrence of lymph node metastases from papillary thyroid microcarcinoma
(PTMC), the pattern of nodal metastasis has been rarely studied. We evaluated the pattern and factors predictive of central
cervical metastasis from PTMC.

Methods  Seventy-two patients with PTMC underwent total thyroidectomy and central neck dissection, including three who underwent therapeutic

Abstract
Background  Currently, a large proportion of individuals undergo thyroidectomy as a diagnostic procedure for cancer. The objective of
this work was to evaluate the molecular phenotype of differentiated thyroid cancer (DTC) and benign thyroid lesions to identify
molecular markers that allow for accurate thyroid cancer diagnosis.

Methods  Tissue microarrays consisting of 100 benign and 105 malignant thyroid lesions, plus 24 lymph node samples, were stained for
