Papillary carcinoma of the thyroid is a slow-growing cancer that typically develops in only one lobe of the thyroid gland. Low power: These tumors are made up of pseudostratified columnar cells arranged in papillary structures, often resembling endometrial or colonic adenocarcinomas. Papillary thyroid cancer or papillary thyroid carcinoma is the most common type of thyroid cancer, representing 75 percent to 85 percent of all thyroid cancer cases. Instead, they may have supranuclear and subnuclear cytoplasmic vacuoles, and thus can easily be mistaken for metastatic adenocarcinoma. Results: Civantos F, Nadji M, Albores-Saavedra J, Morales A.
