Tall cell variant of papillary thyroid cancer.

Papillary histologic type is the most common form of thyroid carcinoma amounting to 85% cases. This pathology presents a rather good prognosis, but a few years ago, new subtypes have been described. Some of these variants show a fairly good prognosis i.e follicular, macropapillary, encapsulated while others appear to have a decidedly worse one, columnar cells, diffused sclerosing, or even to be clearly malignant as in the case of the tall cell variant. The authors report a case treated by a combined surgical and radiometabolic therapy and evidence the main characteristics of this rare and underestimated neoplasia.
