lymphocytic thyroiditis
progressive cellular infiltration of the thyroid gland, predominantly by lymphocytes, and replacement by fibrous tissue, resulting in hypothyroidism, associated with the presence of autoantibodies against thyroglobulin, follicular cell microsomes, and a second colloid antigen. It occurs in dogs, particularly Beagles, obese (OS) chickens, buffalo rats and primates. The disease has some similarity to Hashimoto's disease of humans.

Comment: These results indicate that chronic lymphocytic thyroiditis is common among patients with chronic fatigue, that measuring thyroid autoantibodies in the blood will fail to detect thyroiditis in half of these individuals, and that treatment with thyroid hormone relieves fatigue in patients with chronic lymphocytic thyroiditis, whether or not their TSH level is elevated.
