What are dysplastic nodules?
The term dysplastic nodule replaces older terms like adenomatous hyperplasia and macroregenerative nodule and refers to a nodular region of hepatocytes with dysplasia but without definite malignancy, which represent an intermediate step in the pathway of hepatocarcinogenesis in cirrhosis. Dysplastic nodules are considered neoplastic, premalignant nodules.

What causes thyroid nodular hyperplasia?
Its development is influenced by environmental factors, the most important of which is iodine deficiency, and by genetic factors. In the form traditionally known asendemic goiter, the disease is due to low iodine content of the water and soil, and it can be largely prevented by the addition of iodine to common salt.

Stress alone will not cause a thyroid disorder, but it can make the condition worse. The impact of stress on the thyroid occurs by slowing your body's metabolism. This is another way that stress and weight gain are linked.
Can a thyroid nodule cause weight gain?
Most people who have thyroid nodules lead a normal life. You might need to check in with your doctor more often, but there usually are no complications. If you do have complications, they can include problems swallowing or breathing. You may also sustain significant weight gain or weight loss.
How do I know if my thyroid nodule is benign?
Fine-needle biopsy: With this test, your provider uses a very thin needle to take a sample of cells from one or more thyroid nodules. They then send the samples to a laboratory for evaluation. Most nodules are noncancerous. However, if the test results are inconclusive, your provider may repeat this test.
What percentage of benign thyroid nodules become malignant?
Only ~8% of thyroid nodules are cancerous, so the vast majority are non-cancerous (benign). When the nodule is benign, guidelines recommend repeat ultrasound evaluation and repeat biopsy if there is significant growth of the nodule.
Can an ultrasound determine if a thyroid nodule is benign?
The vast majority — more than 95% — of thyroid nodules are benign (noncancerous). If concern arises about the possibility of cancer, the doctor may simply recommend monitoring the nodule over time to see if it grows. Ultrasound can help evaluate a thyroid nodule and determine the need for biopsy.

Why is hyperplasia of lymph nodes considered a cause of hyperplasia?
To date, the causes of hyperplasia of lymph nodes are considered as the reasons for their increase, which is the immune response to any pathological process that makes changes both in the dynamics of tissue metabolism of the lymph node, and in the ratio of certain cells.
What is hyperplasia in biology?
In fact, hyperplasia (Greek - over education) is a pathological process associated with an increase in the intensity of reproduction (proliferation) of tissue cells of any kind and localization. This process can begin anywhere, and its result is an increase in the volume of tissues. And, in fact, such hypertrophic cell division leads to the formation of tumors.

Why do lymph nodes have hyperplasia?
To date, the causes of hyperplasia of lymph nodes are considered as the reasons for their increase, which is the immune response to any pathological process that makes changes both in the dynamics of tissue metabolism of the lymph node, and in the ratio of certain cells. For example, in response to genetically distinct cells (antigens) in the lymph node, the production of lymphocytes and mononuclear phagocytes (macrophages) increases; when bacteria and microbes get into the lymph nodes, they accumulate the products of their vital activity and neutralized toxins. And in the case of oncology, lymph node hyperplasia can involve any of their cells in the pathological process of proliferation. This causes an increase in the size, a change in the shape and structure of the fibrous capsule of the lymph node. Moreover, the tissues of the lymph nodes can sprout beyond the capsule, and in the case of metastases from other organs, they are replaced by their malignant cells.
Where does follicular hyperplasia occur?
These processes occur in the cortex of the lymph nodes. In this case, the secondary follicles behave quite aggressively, displacing the remaining cells, including lymphocytes.
What is a hyperplastic thyroid nodule?
A hyperplastic nodule of thyroid is characterized by architectural and cytologic heterogeneity, usually with abundant colloid and often with subfollicle formation within larger follicles. and cytology make distinction of hyperplasia from adenoma difficult.
What is the classification of a follicular nodule?
The morphologic classification of cellular follicular nodules in nodular glands can be extremely difficult. Hyperplasia may be extremely difficult to distinguish from neoplasia. Classical guidelines that allow distinction of a hyperplastic nodule from a follicular adenoma include the following: (i) multiple lesions suggest hyperplasia whereas a solitary lesion is likely to be neoplastic, (ii) a poorly encapsulated nodule is likely hyperplastic; a well developed capsule suggests a neoplastic growth, (iii) variable architecture reflects a polyclonal proliferation whereas uniform architecture suggests a monoclonal neoplastic growth, (iv) cytologic heterogeneity suggests hyperplasia; monotonous cytology is characteristic of neoplasia, (v) the presence of multiple lesions in hyperplasia means that areas similar to the lesion in question will be present in the adjacent gland; in contrast, neoplasms have a distinct morphology compared with the surrounding parenchyma, (vi) classically hyperplastic nodules are said not to compress the surrounding gland whereas neoplasms result in compression of the adjacent parenchyma. For the most part, large nodules in multinodular glands tend to be incompletely encapsulated and poorly demarcated from the internodular tissue. However, in some glands, large encapsulated lesions with relatively monotonous architecture
What is an atypical adenomas?
Atypical adenomas are highly cellular tumours with unusual gross and/or histologic appearances that suggest the possibility of malignancy but these tumours lack evidence of invasion. They may have necrosis, infarction, numerous mitoses or unusual cellularity. Many so-called "atypical adenomas" are indeed papillary carcinomas. The distinction of an encapsulated follicular variant papillary carcinoma from follicular adenoma relies on cytologic characteristics. The presence of the cytologic features of papillary carcinoma described below should indicate that diagnosis, despite lack of invasion. Whether some follicular nodules classified histologically as adenomas have the biologic potential to become carcinoma is not clear; aneuploid cell populations
What are the characteristics of follicular cells?
The follicular cells are monotonous with elongated, bland nuclei and micronucleoli. Worrisome features include nuclear crowding, altered polarity, pleo-morphism, macronucleoli and coarse chromatin. The main practical role of cytology is to distinguish a colloid nodule or papillary carcinoma from a follicular neoplasm.
What is a follicular lesion?
On aspiration cytology, the diagnosis of "follicular lesion" covers both follicular adenoma and follicular carcinoma, which are difficult if not impossible to distinguish because the diagnostic criteria do not rest on cytologic characteristics.
What is a sporadic nodular goitre?
Sporadic nodular goitre is characterised by numerous follicular nodules with heterogeneous architecture and cytology, features that have suggested a hyperplastic rather than neoplastic pathogenesis (7-10). The gland may be distorted by multiple bilateral nodules and can achieve weights of several hundred to a thousand grams, but this disorder is often identified as a dominant nodule in what clinically appears to be an otherwise normal gland. Histologically, the nodules are irregular; some are poorly circumscribed while others are surrounded by scarring and condensation of thyroid stroma, creating the appearance of complete encapsulation. They are composed of follicles of variable size and shape. Some follicles are large, with abundant colloid surrounded by flattened, cuboidal or columnar epithelial cells, often with cellular areas composed of small follicles lined by crowded epithelium with scant colloid in a small lumen, alone or pushing into large colloid-filled follicles as "Sanderson's polsters" (Figure 1). There may be focal necrosis, haemorrhage with haemosiderin deposition and cholesterol clefts, fibrosis, and granulation tissue; these degenerative changes are usually found in the centre of large nodules, creating stellate scars.
What is thyroid follicular hyperplasia?
Thyroid Follicular Hyperplasia And Neoplasia. Follicular nodules are the most commonly encountered problems in the surgical pathology of the thyroid. These lesions can be classified along the full spectrum of thyroid pathology from hyperplastic nodules to benign follicular adenomas and malignant fol-licular carcinomas.
How to remove cancerous nodules?
Surgery. A common treatment for cancerous nodules is surgical removal. In the past, it was standard to remove a majority of thyroid tissue — a procedure called near-total thyroidectomy. However, today more limited surgery to remove only half of the thyroid may be appropriate for some cancerous nodules. Near-total thyroidectomy may be used depending on the extent of the disease.
