see lymphocytic thyroiditis (below).

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.
