Sixty patients with goiter, aged 3 to 16 years, 58 girls, were studied for evidence of chronic lymphocytic thyroiditis (CLT). Thirty eight patients, 63%, presented two or more diagnostic elements of TLC, according to Fisher's criteria, with a high frequency of thyroid function involvement (47.4% had hypothyroidism and 18.4% had hyperthyroidism). The rest of the patients with diffuse goiter (37%) did not meet Fisher's criteria, they were mostly euthyroid (95%) and they were designated "non thyroiditis goiter". All patients with probable CLT had positive antimicrosomal antibodies at relatively high titer (greater than 1 x 600 in 71% of the cases) and 32% of them had both antimicrosomal and antithyroglobulin antibodies. In the "non thyroiditis goiter" group we found 28% of children with positive antimicrosomal antibodies at low titers (1 x 100 and 1 x 400, respectively). In a control group of 28 children of similar ages, without endocrine diseases neither familiar history of thyroid diseases only 3 (11%) cases showed positive antimicrosomal antibodies, always at low serum titers.
