BACKGROUND Papillary thyroid carcinomas represent a diversity of morphologic subtypes
and variants, but to the authors' knowledge the prognostic significance of subclassification is …

Background. The influence of various clinicopathologic features on survival of patients with
papillary thyroid carcinoma has been examined. In particular, histologic grade, which was …

Many histological variants of PTC have been described and some are known to have
prognostic significance. However, their relative frequencies and associated …

Background: Our understanding of the natural history of differentiated thyroid carcinoma has
improved with the definition of prognostic factors. These prognostic factors have helped us …

Papillary carcinoma is the most common malignant tumor of the thyroid. It has a variable
macroscopic appearance that differs according to the variant microscopic morphologies and …

The aim of this study was to assess the prevalence, prognostic factors, and long-term
outcome of tall cell variant (TCV) in comparison with the conventional forms of papillary …

Aims: Papillary thyroid carcinoma (PTC) is classified into two subgroups—common type and
other histological variants. Correlations between further subgrouping of the common type …

A number of histologic variants of well‐differentiated papillary carcinoma have been found to
be associated with more aggressive tumor behavior. Tall cell, columnar cell, diffuse …

Background. Multivariate analyses in papillary thyroid carcinoma (PTC) have shown that
age, tumor size, local invasion and distant metastasis are independent predictive variables …

Papillary thyroid carcinomas are the most common endocrine cancer and are usually
associated with good survival. However, some variants of papillary thyroid carcinomas may …
