Among these tumors, certain histological variants, such as the diffuse sclerosing and tall cell carcinoma, are characterized by a more aggressive behavior. and Marc Pusztaszeri, M.D. 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 higher frequency of stromal lymphoid infiltrate. Papillary thyroid carcinoma is given a nodal stage of 0 or 1 based on the presence or absence of tumour cells in a lymph node and the location of the involved lymph nodes. FOIA Aggressive form: The tall-cell variant of papillary thyroid cancer is a more aggressive tumor than common-type papillary cancer. I. 1 These tumors are diagnosed using characteristic nuclear morphology; however, within the classification of "papillary thyroid carcinoma," there exist several distinct architectural and cytologic subtypes. Tall cell variant (TCV) of papillary thyroid carcinoma (PTC), an aggressive form of thyroid cancer, is characterised by 50% of cells with height that is three times greater than the width. To allow surgeons to determine aggressiveness of the tumor before operation, it is important for pathologists to detect tall cell features correctly by fine-needle aspiration cytology (FNAC).
