Solitary thyroid nodules are more common in females yet more worrisome in males. Other associations with neoplastic nodules are family history of thyroid cancer and prior radiation to the head and neck. Solitary thyroid nodules are mostly benign colloid nodules. The second most common type is follicular adenoma. [25]
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.
[4] [5] It can be distinguished from subacute granulomatous thyroiditis by lack of pain, presence of TPO or thyroglobulin (Tg) antibodies, and normal inflammatory markers. [4] [5] Fine needle aspiration (FNA) should be performed in patients who also have a thyroid nodule to rule out thyroid cancer. [5]
In case of Riedel's thyroiditis, fibrosis extends beyond the capsule and involves contiguous neck structures, clinically simulating thyroid carcinoma. There is a rapid thyroid enlargement. Compression of trachea, dysphagia are probable outcomes. Marked thyroid follicular cell atrophy confirms hypothyroidism.
Treatment of a thyroid nodule depends on many things including size of the nodule, age of the patient, the type of thyroid cancer, and whether or not it has spread to other tissues in the body. If the nodule is benign, patients may receive thyroxine therapy to suppress thyroid-stimulating hormone and should be reevaluated in six months. [2]
These nodules grow up at varying rates and secrete thyroid hormone autonomously, thereby suppressing TSH-dependent growth and function in the rest of gland. Inactive nodules in the same goitre can be malignant. [17] Thyroid cancer is identified in 13.7% of the patients operated for multinodular goitre. [18]
Thyroid disease is a medical condition that affects the function of the thyroid gland.The thyroid gland is located at the front of the neck and produces thyroid hormones [1] that travel through the blood to help regulate many other organs, meaning that it is an endocrine organ.
Treatments for this disease depend on the type of thyroiditis that is diagnosed. For the most common type, which is known as Hashimoto's thyroiditis, the treatment is to immediately start hormone replacement. This prevents or corrects the hypothyroidism, and it also generally keeps the gland from getting bigger.
