Hashimoto's thyroiditis, also known as chronic lymphocytic thyroiditis, Hashimoto's disease and autoimmune thyroiditis, is an autoimmune disease in which the thyroid gland is gradually destroyed. [7] [1] Early on, symptoms may not be noticed. [3] Over time, the thyroid may enlarge, forming a painless goiter. [3]
Hashimoto’s disease is an autoimmune condition in which your immune system mistakenly attacks this gland, reducing thyroid hormone production and symptoms that affect your whole body ...
Thyroid lymphoma is a rare cancer constituting 1% to 2% of all thyroid cancers and less than 2% of lymphomas. Thyroid lymphomas are classified as non–Hodgkin's B-cell lymphomas in a majority of cases, although Hodgkin's lymphoma of the thyroid has also been identified.
However, that theory is also controversial since Hashimoto's thyroiditis and chronic lymphocytic thyroiditis (neoplasms to be shown [clarification needed] squamous metaplasia) are not associated with SCT. Primary STC is usually diagnosed in both lobes of the thyroid gland. The histopathology of STC shows a squamous differentiation of tumor cells.
Most commonly an ultrasound is performed to confirm the presence of a nodule, and assess the status of the whole gland. Measurement of thyroid stimulating hormone and anti-thyroid antibodies will help decide if there is a functional thyroid disease such as Hashimoto's thyroiditis present, a known cause of a benign nodular goitre.

In 1968, a reduced T4 half-life in athletes was discovered. This was the first awareness of thyroid hormone concentration alterations that were not a result of thyroid gland or pituitary dysfunction. In 1971, they also found a transient increase in T4 during bicycle training. [2]
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.
