Noninvasive Follicular Thyroid Neoplasm With Papillary Like Nuclear Features
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, necessitating a new classification as it was recognized that encapsulated tumors without invasion have an indolent behavior, and may be over-treated if classified as a type of cancer. Signs and symptoms The clinical presentation of the patients is identical to other thyroid tumors, where there is usually a painless, asymptomatic, mobile thyroid gland nodule or enlargement. Depending on the size, additional symptoms of hoarseness, difficulty swallowing, or other compression symptoms may be experienced. In nearly all cases, the patients do not have any thyroid hormone dysfunction (hyperthyroidism or hypothyroidism – respectively, excessive or low hormone levels). Genetics This tumor shows a very high association with other follicular-pattern tumors, with Ras gene, RAS m ...

Papillary Thyroid Carcinoma
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.Chapter 20 in: 8th edition. It occurs more frequently in women and presents in the 20–55 year age group. It is also the predominant cancer type in children with thyroid cancer, and in patients with thyroid cancer who have had previous radiation to the head and neck. It is often well-cellular differentiation, differentiated, slow-growing, and localized, although it can metastasis, metastasize. Diagnosis Papillary thyroid carcinoma is usually discovered on routine examination as an asymptomatic thyroid nodule that appears as a neck mass. In some instances, the mass may have produced local symptoms. This mass is normally referred to a Needle aspiration biopsy, fine needle aspiration biopsy (FNA) for investigation. FNA accuracy is very high and it is a process widely used in these cases. Other investigation methods inclu ...
