What autoimmune disorder is associated with the destruction of thyroid tissue?

• A. Graves' disease
• B. Hashimoto's thyroiditis
• C. Cushing's syndrome
• D. Thyroid storm

Answer: (B)

Hashimoto's thyroiditis is an autoimmune disorder characterized by the immune system attacking the thyroid gland, leading to its destruction. This condition is the most common cause of hypothyroidism, where the thyroid does not produce enough hormones due to the loss of functional thyroid tissue. Over time, the infiltration of lymphocytes and the presence of antibodies against thyroid peroxidase and thyroglobulin contribute to the inflammation and destruction of the thyroid gland. In contrast, Graves' disease is also an autoimmune disorder but is primarily associated with hyperthyroidism, resulting from antibody stimulation of the thyroid. Cushing's syndrome is a hormonal disorder caused by excessive cortisol production, and thyroid storm is a severe form of hyperthyroidism that can occur in patients with untreated Graves' disease, characterized by a sudden and severe exacerbation of symptoms. Thus, Hashimoto's thyroiditis specifically relates to the autoimmune destruction of thyroid tissue, leading to its impaired function.
