Columnar cell variant of papillary carcinoma (CCV-PC) thyroid is a rare and aggressive tumor composed of tall columnar cells that form papillae, glands and solid structures. This paper describes fine needle aspiration (FNA) cytologic features in a case of CCV-PC occurring in the right thyroid lobe o
## Abstract 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 sclerosing, solid/trabecular, and insular variants of well‐differentiated papillary thyroid cancer are all p
## Background: The tall cell variant of papillary carcinoma of the thyroid (tcv) is characterized by the proliferation of oxyphilic, tall, columnar cells with a height-to-width ratio of at least 2:1. tcv exhibits more aggressive clinical behavior than conventional thyroid papillary carcinoma (cpc).
Cytologic reports of the aggressive tall-cell and diffuse sclerosing variants of papillary carcinoma have emphasized features such as tall and large cells, increased nuclear size, nuclear pleomorphism, intranuclear pseudoinclusions, three-dimensional tissue fragments, squamous-like cells, and dense
