Colloid nodules may be initially identified as an unspecified kind of thyroid nodule. Follow-up examinations typically include an ultrasound if it is unclear whether or not there really is a nodule present. Once the presence of a nodule has been confirmed, the determination of the kind of thyroid nodule is done by fine needle aspiration biopsy. [7]
An autonomous thyroid nodule or "hot nodule" is one that has thyroid function independent of the homeostatic control of the HPT axis (hypothalamic–pituitary–thyroid axis). According to a 1993 article, such nodules need to be treated only if they become toxic; surgical excision (thyroidectomy), radioiodine therapy, or both may be used. [32]
Nodular goitres are either of one nodule (uninodular) or of multiple nodules (multinodular). [14] Multinodular goiter (MNG) is the most common disorder of the thyroid gland. [15] Growth pattern. Uninodular goitre: one thyroid nodule; can be either inactive, or active (toxic) – autonomously producing thyroid hormone.
Thyroid nodules are often found on the gland, with a prevalence of 4–7%. [59] The majority of nodules do not cause any symptoms, thyroid hormone secretion is normal, and they are non-cancerous. [60] Non-cancerous cases include simple cysts, colloid nodules, and thyroid adenomas.
Regular monitoring mainly consists of watching for changes in nodule size and symptoms, and repeat ultrasonography or needle aspiration biopsy if the nodule grows. [8] For patients with benign thyroid adenomata, thyroid lobectomy and isthmusectomy is a sufficient surgical treatment.
Certain medications can have the unintended side effect of affecting thyroid function. While some medications can lead to significant hypothyroidism or hyperthyroidism and those at risk will need to be carefully monitored, some medications may affect thyroid hormone lab tests without causing any symptoms or clinical changes, and may not require treatment.
It shows marked hyperplasia of thyroid follicular cells, generally more so than toxic multinodular goitre, forming papillae into the thyroid follicles, and with scalloping of the peripheral colloid. Graves' disease is an autoimmune disorder, in which the body produces antibodies that are specific to a self-protein - the receptor for thyroid ...
The thyroid gland is extremely painful, rigid, and swollen, which can be symmetrical or asymmetrical. [2] Approximately half of affected adolescents and two-thirds of adults have widespread thyroid gland involvement. [3] [5] Thyroid nodules are seen in one-fourth of adult patients. [6] The surrounding skin is occasionally warm and erythematous.
