The pathologic diagnosis of papillary thyroid carcinoma includes several histologic variants, such as the tall cell, columnar cell, oxyphil cell, diffuse sclerosing, poorly differentiated, diffuse follicular, and hyalinizing trabecular types.1,2 The presence of these features may be clinically significant, particularly in the cases of the tall cell and diffuse sclerosing variants, which are associated with poorer clinical outcomes.
