Papillary carcinomas of the breast (PCB), also termed malignant papillary carcinomas of the breast, are rare forms of the breast cancers. [1] The World Health Organization (2019) classified papillary neoplasms (i.e. benign or cancerous tumors) of the breast into 5 types: intraductal papilloma, papillary ductal carcinoma in situ (PDCIS), encapsulated papillary carcinoma (EPC), solid-papillary ...
Histopathology of NIFTP, H&E stain. [1]Noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) is an indolent thyroid tumor that was previously classified as an encapsulated follicular variant of papillary thyroid carcinoma, [2] necessitating a new classification as it was recognized that encapsulated tumors without invasion have an indolent behavior, [2] and may ...
Papillary microcarcinoma is a subset of papillary thyroid cancer defined as measuring less than or equal to 1 cm. [15] The highest incidence of papillary thyroid microcarcinoma in an autopsy series was reported by Harach et al. in 1985, who found 36 of 101 consecutive autopsies to have an incidental microcarcinoma.

Follicular thyroid cancer accounts for 15% of thyroid cancer and occurs more commonly in women over 50 years of age. Thyroglobulin (Tg) can be used as a tumor marker for well-differentiated follicular thyroid cancer. Thyroid follicular cells are the thyroid cells responsible for the production and secretion of thyroid hormones.
Radioactive iodine-131 is used in patients with papillary or follicular thyroid cancer for ablation of residual thyroid tissue after surgery and for the treatment of thyroid cancer. Patients with medullary, anaplastic, and most Hurthle cell cancers do not benefit from this therapy. [ 2 ]
If the diagnosis of well-differentiated thyroid cancer (e.g. papillary thyroid cancer) is established or suspected by FNA, then surgery is indicated. [50] [51] Surgical resection is the preferred treatment for all biopsy confirmed thyroid cancers. In those with very low risk tumors (such as small papillary tumors without evidence of local or ...
Thyroid follicular adenoma ranges in diameter from 3 cm on an average, but sometimes is larger (up to 10 cm) or smaller. The typical thyroid adenoma is solitary, spherical and encapsulated lesion that is well demarcated from the surrounding parenchyma. The color ranges from gray-white to red-brown, depending upon the cellularity of the adenoma
Dr. Yuri Nikiforov (Russian: Юрий Ефимович Никифоров, romanized: Yury Yefimovich Nikiforov; born 12 September 1962) is an American scientist who revolutionized the understanding of thyroid cancer, most recently winning a two-year battle in which the World Health Organization agreed in 2017 to reclassify non-invasive thyroid tumors to non-cancerogenic liaisons.
