This cancer has recently been reclassified as a neoplasm of low malignant potential and is now termed “noninvasive follicular thyroid neoplasm with papillarylike nuclear features” (NIFTP). Panel C shows the encapsulated follicular variant of papillary thyroid carcinoma without invasion, which until recently represented 17% of all papillary thyroid carcinomas.

Celulas foliculares anormales que contienen niucleos alargados hipercromáticos con pseidoinclusiones nucleares. Hay hipercelularidad, crecimiento nuclear, hipercromasia e incremento del tamaño del nucleo con respecto al citoplasma. FIGURA D: nódulo sospechoso de malignidad. El resultado de patología fue un adenoma. Las células foliculares tienen tamaño normal pero forman micro foliculos. El paciente se sometió a tiroidectomía y la biopsia demostró hiperplasia. Algunas células muestran crecimiento nuclear. Las células foliculares están espaciadas y tienen una forma pequeña y nuclear.

ğNA is not recommended for nodules that are functional on scintigraphy (see difference in recommendations for children Section 8.4.).

In light of the low clinical risk, nodules 20 mm ¡ Low US risk thyroid lesions only when >20 mm and increasing in size or associated with a risk history and before thyroid surgery or minimally invasive ablation therapy Thyroid FNA should always be performed under US guidance because it makes the procedure safer, more reliable, and more accurate. All patients with a palpable thyroid nodule or clinical risk factors should undergo US examination. Thus, clinical and US risk factors for malignant disease should always be reviewed. Most patients with thyroid nodules are asymptomatic, but the absence of symptoms does not rule out malignancy. Accordingly, the main clinical challenge in the treatment of these patients is to rule out malignancy. In most cases, they appear in euthyroid persons and cause neither compressive symptoms nor cosmetic concerns.

Thyroid nodules are a common finding because they are detected in up to 50 to 60% of healthy people.

This tumor shift may be due to the increasing use of neck ultrasonography or other imaging and early diagnosis and treatment (10), trends that are changing the initial treatment and follow-up for many patients with thyroid cancer. Moreover, 25% of the new thyroid cancers diagnosed in 1988–1989 were £1 cm compared with 39% of the new thyroid cancer diagnoses in 2008–2009 (9). Almost the entire change has been attributed to an increase in the incidence of papillary thyroid cancer (PTC). In the United States, approximately 63,000 new cases of thyroid cancer were predicted to be diagnosed in 2014 (8) compared with 37,200 in 2009 when the last ATA guidelines were published.  Espongiformes (más de la mitad del nódulo formado porĭiámetro 90%) of all thyroid cancers (7).  Hipoecogenicidad (nódulo más oscuro que parénquima)
