BACKGROUND Thyroid papillary carcinoma of columnar cell type is considered an
uncommon histologic subtype of papillary carcinoma characterized by its morphologic …

The columnar cell variant of thyroid papillary carcinoma is an aggressive tumor associated
with widespread dissemination and a fatal outcome. We report a case of a 29-year-old white …

BACKGROUND The columnar cell variant of papillary thyroid carcinoma (PTC‐CCV) is a
rare entity that demonstrates a more aggressive clinical course compared with the more …

The majority of papillary thyroid carcinoma is indolent and associated with long-term
survival. The columnar cell variant, however, is a rare subtype that is variable in biological …

A rare case of columnar cell carcinoma of the thyroid gland is reported. The tumor was
characterized by a predominantly papillary proliferation of tall columnar cells with marked …

BACKGROUND: The columnar and tall cell variants of papillary thyroid carcinoma (PTC) are
uncommon variants and have generally been regarded as more aggressive forms in …

The tall cell variant of thyroid papillary carcinoma differs from classic papillary carcinoma in
its more aggressive clinical behavior, cell type (columnar amphophilic to oxyphilic) and …

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 …

Papillary thyroid carcinomas (PTC) are the most common thyroid tumors that usually have a
good prognosis. Recurrence, metastases, and cancer death may occur in a few patients and …

We analyse a new variety of papillary carcinoma of the thyroid, known as the tall cell variant.
The lesion is characterized by a papillary cancer (PCT) in which more than 30% of the …
