Fifty - four children with chronic lymphocytic thyroiditis (CLT) were reviewed retrospectivety.All patients had clinical manifestation of diffused goiter and among them 45 patients were with positive antithyroglobulin antibody (TGA) and 48 patients were positive antimicrosomal antibody (MCA). The laboratory tests demonstrated that 43 cases were entyroid

1 case hyperthyroidism and 10 cases hypothyroidism. The clinical features and laboratory results of CLT in children are not as typical as those in adults. For any child with goiter or hypothyroidism

TGA/MCA positive or with characteristic cytological features in fine needle aspirotion biopsy (FNAB) the diagnosis of CLT should be considered.
